texte = >[ShowIf [url][wogroup1datarq][/url]![raw][wogroup1datarq][/raw]] >[wogroup1datarq] >[/ShowIf]That [URL] part is messing you up. ShowIf works just like an algebraic equation, in that both sides of the equation have to be acted upon in the same way. For instance, with the [URL] stuff in there, you get something that looks like:%5Bwogroup1datarq%5D ! [wogroup1datarq, which is of course always trueI suppose you could wrap the right-hand side of the equation inside a [URL] in order to even things up.In any event, you can learn a valuable debugging lesson here: any time something doesn't seem to work right, start breaking the problem down into smaller pieces. In your case, try displaying each portion of the ShowIf equation separately on the page, like so:Left side of ShowIf: |[url][wogroup1datarq][/url]| Right side of ShowIf: |[raw][wogroup1datarq][/raw]|...and you should quickly be able to see what's going on, rather than just guessing at what the inside of [ShowIf] is seeing.Technical Support | ==== eCommerce and Beyond ==== Pacific Coast Software | WebCatalog, WebMerchant, 11770 Bernardo Plaza Court | SiteEdit Pro, PhotoMaster, San Diego, CA 92128 | Typhoon 619/675-1106 Fax: 619/675-0372 | http://www.smithmicro.com/
