Well, I just did two more tests and here are my results:Sending form variables to the page does not override the above values, nor does trying to reset them as INsecure text variables. Only resetting them as secure text variables allows their values to be changed into something which is clearly less than global.So don't be deceived by the terminology. The tags above do not create global values like the docs say. Instead they create values which can be changed via [text secure=T], and that makes them fall somewhere in between form variables and global tags in the variable hierarchy.Based on my tests, the following list includes the only TRUE global tags in the webdna language. These variables cannot be overridden by secure text variables or by any other variables, which means they are truly global in nature:BrowserName HTTPMethod IsSecureClient Password Referrer ThisFile ThisURL UserName Sincerely, Kenneth Grome--------------------------------------------------- WebDNA Professional Training and Development Center 175 J.
