Using Umbraco.helper in a partial view @functions
In a prtial view, I have some code in an
```
@functions{}
```
section which tries to use Umbraco.Helper to get the url of a media image given its id. ie.
```
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
...

@functions{

    public class rowOutput{
            ...
            int mediaId = Int32.Parse(pValue);
       umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);       pValue = umbracoHelper.TypedMedia(mediaId).Url.ToString();
       ...
       }
...
}
```
but I get this error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0103: The name 'umbracoHelper' does not exist in the current context

Source Error:

Line 641: int mediaId = Int32.Parse(pValue); Line 642: umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);
Line 643: pValue = umbracoHelper.TypedMedia(mediaId).Url.ToString();

How can I add reference to Umbraco.Helper in this partial view?

Many thanks

Hi Tim C

I think this is just because the umbracoHelper variable isn't declared in your function eg:
```
 int mediaId = Int32.Parse(pValue);
 var umbracoHelper = new 
 Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);
 pValue = umbracoHelper.TypedMedia(mediaId).Url.ToString();
```
But equally you can access the UmbracoHelper from the property on the partial view eg:
```
 int mediaId = Int32.Parse(pValue);
 pValue = Umbraco.TypedMedia(mediaId).Url.ToString();
```
Would have the same result, but not involve creating a new helper...

regards
