Hi Adrian,

Okay I will try to guide you step by step so we are get it work for you.

1. Add the field on the document type for e.g frontpage. Go the setting section --> Document type (I have made a screenshot)

2. Then we need to create a XSLT file. Go to developer section, then right click on the XSLT folder. Give the file a name (e.g Redirect) and choose clean. There are some build in templates for e.g navigation and so on. When you create the file don´´t remove the tick in Create Macro.

When you have created the XSLT plaste in this code, and then save the file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
    version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxml="urn:schemas-microsoft-com:xslt"
    xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" xmlns:Examine="urn:Examine" xmlns:Flexit.PdfThumbnails="urn:Flexit.PdfThumbnails" 
    exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets Examine Flexit.PdfThumbnails ">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">    
    
<xsl:if test="string-length($currentPage/externalRedirect)!=0">

<script>
    document.location.replace("<xsl:value-of select="$currentPage/externalRedirect" />");
</script>
</xsl:if>

</xsl:template>

</xsl:stylesheet>

3. Go back to the settings section choose the templates forlder and choose the template where you what the redirect. It could be on the frontpage. (In my example I have choosen the frontpage)

Then click at the button or the click at the arrow that i have marked. When you done that you chould get at list of your macros, could be XSLT or Razor. There you need to find the macro with the name you gave your XSLT when you created it.

When click okay and save the template. After that this should be added in your template.

4. Now go to content page and choose a page with the field where you can add the URL. In my example I added the field to the frontpage, and now I write the URL that the page should redirect to. (See sreenshot)

I hope these screenshot will make it easier to you to get the redirect working.If you have any question about this keep asking. Since you´re relatively new to Umbraco I thik that you shold take a look at this:

http://our.umbraco.org/wiki/reference/xslt

http://our.umbraco.org/documentation/Reference/Templating/managing-templates

If you like video tutorials I will recommend you to see this free videos: http://umbraco.tv/videos/umbraco-v7/implementor/ Although these are for Umbraco 7, is most of the basic principles in Umbaco, which also acts in the previous versioer. except the Razor path that will need (Umbraco 4.7 or later if I remember correctly).

Here is some video tutorials about XSLT, but this need that you subscribe to the Umbraco.tv. http://umbraco.com/help-and-support/video-tutorials/umbraco-fundamentals/xslt-in-umbraco-45.aspx

I hope this helps you, and make sense.
