Hello , My problem is that: I have ZPT pages, and scripts. I want to check some infos with SQL query. This an example: script: ------- ss=context.REQUEST.SESSION r=0 uusr=usr.lower() result=context.LoginScripts.dbcheckUsrPwd(uusr,pwd) if len(result)>0: r=1 ss['userid']=row[0] ss["username"]=usr ss["full username"]=row[1] return(r) zsql: ----- params: usr,pwd select * from inst_prguser where webusr=<dtml-sqlvar usr type="string"> and webpwd=<dtml-sqlvar pwd type="string"> The result is: "Missing input variable, usr". I think this is wrong in zsql - it have wait for dtml-var. But how to I do it in good way to the zsql get good parameters ? Thanx. -- Best regards, fowlertrainer mailto:fowlertrainer@anonym.hu
