Hi, I was trying to make a hitcounter ZClass (cHitCounter). But I've got problems with it. The ZClass has one property (hitCount : int) Calling the property is no problem. But I can't seem to increment it! Nothing works (and I tried a lot!) : 1. I made an 'inc' DTML method in the product pHitCounter, which only contains this line : <!--#call "manage_changeProperties(hitCount=hitCount+1)"--> If I now make an instance of this class and from a dtml document call : <!--#with counter--> <!--#call inc--> <!--#var hitCount--> <!--#/with--> Going to this page doesn't increments the hitCount at all! 2. Also this doesn't work either : <!--#with counter--> <!--#call "manage_changeProperties(hitCount=hitCount+1)"--> <!--#var hitCount--> <!--#/with--> I tried several things, like changing the url, but or I get an error relating the site is down, or I get no error at all, but also no increment! What am I doing wrong??? --- can also somebody tell me, why I get an error using : <!--#var counter.hitCount--> and not when using <!--#with counter--> <!--#var hitCount--> <!--#/with--> Tom.
