Before assigning it to src

Check like this

if(imgRolloverOff != null)
{
your image tag 
}

Hi Akeem.

The errormessage "Input string was not in a correct format" usally apears when a parse is made from a string to a int. Im guessing that a parse is beeing made in the Umbraco.TypedMedia() function and its causing an error. Probobly because the @CurrentPage.carouselImg3 is null or Empty. You sholud probobly make sure that CurrentPage has a value for carouselImg3 and also that it is of type int.

Try the following:

@if (CurrentPage.HasValue("carouselImg3"))
{
    int mediaId;
    Int32.TryParse(CurrentPage.carouselImg3.ToString(), out mediaId);

    if (mediaId != 0)
    {
        IPublishedContent imgRolloverOf = Umbraco.TypedMedia(CurrentPage.carouselImg3.ToString());
        if (imgRolloverOf != null)
        {
            <img class="img-responsive center-block" src="@imgRolloverOf.Url"/>
        }
    }
}

Hope this works out for you!!

PS.

Just to double-check, CurrentPage.carouselImg3 is of datatype mediapicker?

enter image description here

Please help me . I dont know how to solve this issue . My code now :

 <div class="item">


                        @if (CurrentPage.HasValue("carouselImg3"))
                        {
                            int mediaId;
                            Int32.TryParse(CurrentPage.carouselImg3.ToString(), out mediaId);

                            if (mediaId != 0)
                            {
                                IPublishedContent imgRolloverOf = Umbraco.TypedMedia(CurrentPage.carouselImg3.ToString());
                                if (imgRolloverOf != null)
                                {
                                    <img class="img-responsive center-block" src="@imgRolloverOf.Url" />
                                }
                            }
                            <a class="carousel-caption" href="@Umbraco.NiceUrl(@Convert.ToInt32(@Umbraco.Field("carousel3Link").ToString()))"></a>

Could it be this line that breaks for you?

 <a class="carousel-caption" href="@Umbraco.NiceUrl(@Convert.ToInt32(@Umbraco.Field("carousel3Link").ToString()))"></a>

Have you tried uncommenting the above line?

What datatype is carousel3Link? It looks like it could be a contentpicker, is that correct? In that case, could you try:

 <div class="item">
                            @if (CurrentPage.HasValue("carouselImg3"))
                            {
                                int mediaId;
                                Int32.TryParse(CurrentPage.carouselImg3.ToString(), out mediaId);

                                if (mediaId != 0)
                                {
                                    IPublishedContent imgRolloverOf = Umbraco.TypedMedia(CurrentPage.carouselImg3.ToString());
                                    if (imgRolloverOf != null)
                                    {
                                        <img class="img-responsive center-block" src="@imgRolloverOf.Url" />
                                    }
                                }
                            }

                            @if (CurrentPage.HasValue("carousel3Link"))
                            {
                                int nodeId;
                                Int32.TryParse(CurrentPage.carousel3Link.ToString(), out nodeId);

                                if (nodeId != 0)
                                {
                                    IPublishedContent node = Umbraco.TypedContent(CurrentPage.carousel3Link.ToString());
                                    if (node != null)
                                    {
                                        <a class="carousel-caption" href="@node.Url"></a>
                                    }
                                }
                            }

    </div>

HI Dennis,

You are a genius . I was just wondering how you knew that was a contentPicker . Its it works on my development . Now i have to transfer the code to the real site .

Also i just noticed what happened . The content picker is empty . That might be reason its throwing the exception . Am working with the website designer , so am not able to pinpoint what has changed some times in the umbraco admin section ...

However , as part of fixing this issue , i upgraded umbraco for my development site . but it doesnt still work yesterday . Can i still use courier from umbraco 7.4 new version with umbraco previous version . The sites were the same version before when i was using the courier .

Thank you Akeem! :)

I dont know, made sense that it would be a contentpicker. Yes, if the contentpicker if empty i could see why it threw the exception.

About your last question about Courier, you sholud post it as a separate forum thread, since Im not very fimiliar with courier.

Best of luck to you!!!

Have a great day!!
