I think the problem here is that you're setting text variables to blank instead of setting math variables to zero. Blank is not a valid math value, math values have to be numeric -- not blank.Thus, when you try to reset the blank text variable with a math context, it does not work properly, because the original blank value was never a valid math value to begin with, so webcat knows it's a text value and prevents it from being reset as a math value.It seems to me that if you're going to set math values on the page, you should NOT preset them to a blank value with the text context, because they are not text variables. Instead you should be setting them to zero in a math context. If you do this, I think you will find that using a plain [varname] tag further on down the page *will* display the proper math variable value.:)================================ Kenneth Grome, WebDNA Consultant 808-737-6499, http://webdna.net ================================------------------------------------------------------------- Brought to you by CommuniGate Pro - The Buzz Word Compliant Messaging Server.
