And when you say text variables you mean both [TEXT] and [MATH], right?It all seems very clear, except for this side effect. I'm not quite sure how it comes into play. Are you saying that if have the following code:1 [TEXT]var=hello[/TEXT] 2 some stuff 3 [TEXT SECURE=F]var=goodbye[/TEXT] 4 [VAR]then Webcat will now have [VAR] in its hierarchy *twice* but will default to the secure version? That is line 4's [VAR] will evaluate to hello instead of the later defined goodbye? Or will the SECURE=F tag kick [VAR] up a few steps in the hierarchy so that line 4 evaluates to goodbye?If the former (evaluating the secure [VAR] first), we should use SECURE=F in the first instance of the variable to define its place in the hierarchy. Right? If the former, how would WebCat evaluate conflicting tags on the same page (like if someone tries to switch the security of a variable several times in the same page)?If this example doesn't make sense, it's because I'm having trouble coming up with all the possible conflicts of having two variables with the same name.How would WebCat handle this example:on SOMEPAGE.HTML?VAR=10[MATH SECURE=T]VAR=25[/MATH] [MATH SECURE=F]VAR=[VAR]+5[/MATH] would the result be 15 or 30?It all makes my head hurt, Michael############################################################# This message is sent to you because you are subscribed to the mailing list
