OnSubmit Problems...

[Fredde]

I want to prevent the action when a value in "sumtot" is "NaN". According to what I understand returning false from an onSubmit function should cancel the FORM action?!
code:

HTML:
<FORM name=&quot;fm&quot; onSubmit=&quot;return CheckValues()&quot; method=get action=&quot;Save.asp&quot;>

SCRIPT:
function CheckValues() {
if (isNaN(document.fm.sumtot.value) == true) {
alert(&quot;Illegal value&quot;
return false;
}
}

Yes, but you got a little redundant. No need to ask if it's ==true -- you can just evaluate isNaN. Try this, and see if it works:

<FORM name=&quot;fm&quot; onSubmit=&quot;return CheckValues();&quot; method=get action=&quot;Save.asp&quot;>

function CheckValues() {
if (isNaN(document.fm.sumtot.value)) {
alert(&quot;Illegal value&quot;
return false;
}
return true;
}
