Hi Paul. I think I found a solution to the problem. It is a language issue. The label "Figure" was not found in the list of lables. I had a mixture of English and Swedish in the template file and for some reason the Lable text/entry "Figure" was not found when running thru the Citrix Portal. I added this code snippet before inserting the caption:
CaptionLabels.Add Name:="Figure" ' always make sure we have we this label created before we use it

Now it works from both the Terminal Server I am logged in to and also thru the Citrix portal.
Kind Regards /Benble
