Hi

I am new to Umbraco an playing with it for almost 36 hours.

My experience with XSLT is very limited.  I just wanted a list of My images from one of my media folders.

I found the wiki entry "ListFilesFromMediaFolders" (http://our.umbraco.org/wiki/reference/code-snippets/listfilesfrommediafolderxslt) which was very helpful.  But even when I use this code I can't save the xslt because I get an error about a int32 too small or too large. (see below)

My code is just plain default stuf from the example. I pasted for your reference at the bottom of this post.  If i start removing the lines one by one it is this line:

  <xsl:variable name="files" select="umbraco.library:GetMedia($mediaFolderID,1)" />

where i get the error. 

According to my about page, I use umbraco v 4.5.2 (Assembly version: 1.0.3891.20719).  Which i already understood is the latest you can get at the moment of writing

Although I tried searching the forums & wiki, I didn't succeeded in finding a solution.I read about very knowledge people on this forum.  I hope you can help.

Error occured
