setting hidden variables in CGI tasks

Annad

Hi,
Here is my problem with the script for a CGI task I have in the workflow.
The perl script that is executed for a CGI task uses the iwcgicallback to move to one of its successor cgi task.
However this takes place upon a click of a submit button.
When the button is clicked, a TeamSite error occures which states that the session string and some other important parameters are missing for this request to be completed.
So I tried to set hidden parameters for the session string, but it does not seem to see that.

Any ideas on how to use the $cgi->iwcgicallback() and pass in the needed parameters for the next task.

I really appreciate your help.
Thanks,
Anna.
