[Zope] dtml-let and MySQL

Hi, I've tried to write one generic SQL method and passing argument to my SQL method using dtml-let but I got KeyError. I've tried it with dtml-with also but same thing. In my page I use: <dtml-let curpage=total> <dtml-call hitinsert> </dtml-let> and MySQL method is: update zp_stat set <dtml-var curpage> = <dtml-var curpage> + 1 What I want to do, is passing mySQL argument and using one method. Ex:  <dtml-let curpage=astro> <dtml-call hitinsert> </dtml-let> total and astro are INT in my SQL table. I dont know if dtml-let is a right way? Any suggestion to do this?
