I don't know what it does. But what it *doesn't* do is pass on the value of the submit button(s). > Side note to the original poster: in the script that is the target of > the form you are writing, you may be able to test for the presence of > the "submit" variable -- if this value is not present, then the user has > not clicked the Submit button.

I may be wrong about > this, though. Thus if you relied upon testing for the value of the submit button to determine whether the form had been submitted (as opposed to being viewed for the first time) then you're going to get unexpected results. One way to code around it would be to add a hidden field in your form and test for the presence of that rather than the submit button. -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk /* Newton's Law of Gravitation: What goes up must come down.
