    syntax error ?

    Code:
    if (document.forms.item("hidGamChosen") != "") _ 
AND (document.forms.item("hidGamChosen") != null) {
    Can anyone tell me if I've written that one right?
    (I haven't got the _ in the actual code), Thanks.

    First, familiarize yourself with the DOM specs from the W3C.

    Second, do you have a form named "forms"?

    Instead of "AND", use "&&".

    no, but the forms collection seems to work as well as if I name the form, I'll remember the && one.

    Thanks for the suggestions

    Arrow hi

    Why not simply use it this way :

    Code:
    if (document.formname.hidGamChosen != "") && (document.formname.hidGamChosen != null) {

    Yeah, Jonny, that is what I was driving at. I don't think the item collection is part of the standard.

    Wynd found the error though. That's what I get for using entirely too many languages in one day. Another reason to stop using VB: Perl, JavaScript, C++, and Java all have similar syntax.
