Text variable not working properly in web template

Hi there,

I'm having trouble with a customer exit text variable. I use this text variable in a query as a header for a column. When executing the query, the text variable works fine and is shown correctly.

However, I have the same text variable attached to an info field in one of my web templates. When executing the web template no values are shown, the info field does not show up.

What could be the reason for this strange behaviour?

Regards,

Thomas
