[Zope] <dtml-if> no-work

Hi! I have now run into yet another problem on my way to Zope nirvana: I have the following expression: <dtml-var personelID> = <dtml-var personelID_page> <dtml-if "personelID == personelID_page"> .......................... It prints for instance: 1 = 1 But even though it prints that the two vars equals each other, it does not execute the <dtml-if> statement. Is this caused by a integer / string problem? Regards, A n d e r s G a a r s d a l H o l s t
