Your second way is cleaner.
Thank you for that helpful explanation. At least I "get it" now. So as long as I'm just passing strings and numbers, I'm okay. Appears as if the Transcript could use and 'object' type-cast command ala value. go object( param(1) ) get the myProperty of object( param(1) ) Why is Revolution complicated in areas it should be elegant? ~~~ Arthur "Never interrupt your enemy while he is making a mistake." _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
