Variables in Web Templates

Hi There

I have developed a series of simple web templates for profit center reporting i WAD. The queries used in the templates use a variable (0N_PCTR) for selecting from the profit center hierarchy. This works out fine when calling the the first template the variable screen is displayed.

But when the users execute the next template and a variable pop up is displayed it is not possible to change the selection for profitcenter. The select profitcenter/profitcenter group node screen is blank. If i close the web application and start with this report it works fine.

Any ide for solving this problem?
