homeNode is a node above/or the current node and headerImageFolder is a mediapicker property (a media folder is selected) and this contains the id of the selected folder. When i save it i get the following error. However if i hard code the value instead of using the mediafolderId variable in the call to GetMedia it works fine.
Error occured

You should probably check to see if the mediaFolderId returns a result (even if you know that it should). See Lee Kelleher's blog post on how to use GetMedia, it's excellent!
I've noticed that in xslt if you declare a variable set to an id of a node and you dont specify the if test, as kipusoep mentions above, i've almost always get the error you showed above.
why does this not work

I think the problem is, that XSLT doesn't know if $mediaFolderId will be a valid integer, could you try this:
<xsl:variable name="mediaFolderId" select="number($homeNode/data[@alias='headerImageFolder'])" />
You should probably check to see if the mediaFolderId returns a result (even if you know that it should). See Lee Kelleher's blog post on how to use GetMedia, it's excellent!
Sorry, that's not correct, use this instead:
Just another reason to use .NET instead of XSLT ;-)
thanks i'll get that a try
Hi seanrock,

seanrock,
I've posted an issue something similar to you my xslt is as follows:
<xsl:param name="currentPage"/>
<xsl:variable name="ID" select="$currentPage/data [@alias = 'galleryImages']"/>
<xsl:template match="/">
<!-- start writing XSLT -->
<xsl:if test="$ID > 0">
<xsl:variable name="mediaItems" select="umbraco.library:GetMedia($ID, true())"/>
<xsl:for-each select="$mediaItems/node">
<img>
<xsl:attribute name="src">
<xsl:text>/umbraco/imagegen.ashx?image=</xsl:text>
<xsl:value-of select="current()/data[@alias='umbracoFile']"/>
<xsl:text>&width=300</xsl:text>
</xsl:attribute>
</img>
</xsl:for-each>
where galleryImages is the mediapicker property set to a sub folder under the media folder.
is working on a reply...
