When evaluate obj["foo"] and there's no "foo" field on "obj", you get undefined.
And *this[prop].text * is the same as *(this[prop]).text* So when prop is the name of an invalid property (like "myInput6"), it's the same as calling: * (undefined).text* Which is never going to work. Replace your test for *if(this[prop].text)* with *if(prop in this)* -Josh On Tue, Nov 4, 2008 at 2:53 PM, timgerr <[EMAIL PROTECTED]> wrote: > Thnaks for the help, here is the problem that I am getting.
