[Zope] passing the parameters to zsql method

Hello! I'm trying to pass the form parameters from page template to zsql method. A piece of code follows: <form action="clients_add_sql"> <input type="text" name="name"> <input type="text" name="account"> <input type="submit"> </form> clients_add_sql: insert into table(name,account) values (<dtml-sqlvar name type=string>, <dtml-sqlvar account type=string>); the problem is when i click the 'submit' button, the form "clients_add_sql Input Data Enter query parameters:" appears. Does someone know how i can pass the form parameters to zsql method directly? --
