Since the form has yet to besubmitted, there is no value for your [input value] variable. One thingthat is sometimes hard for new users to grasp initially is that webcatalogcan only operate on the template _before_ it's sent to the browser. UnlikeJavascript, which operates in the browser _after_ it's left the server. I'msure you understand this already, I'm just pointing it out in case youhaven't applied that logic thoroughly to this problem. Since when the formis first served by Webcat, there is no value for your [input value]variable. Double check this by viewing your html source in the browser.You'll see literally [input value] in the form. Since there is no valueinitially, it won't be usable in this situation. There are a number ofother approaches that will work, however. Redirect or pass the value froman intermediate form. Redirect would look something like this:[showif [theUser]![raw][theUser][/raw]][redirect /[theUser].tpl][/showif]Using [thisURL] as the form action makes it submit back to itself. At thatpoint, the input variable will have a value. You'll want to add errorchecking or validation to this to prevent blank entries or non-memberlogins, etc.======================Or you could do an intermediate form like this:[showif [theUser]![raw][theUser][/raw]][/showif][showif [theUser]=[raw][theUser][/raw]][/showif]Hope that helps...Mike-------------------------------------------------------------This message is sent to you because you are subscribed to the mailing list .To unsubscribe, E-mail to: To switch to the DIGEST mode, E-mail to Associated Messages, from the most recent to the oldest:
