Object MATH method isNAN

[macmonteiro]

Heloops....

I'm not a little used with JS 'math' object... Look at what we've been trying to do:

<!-- Begin
function verifica(form) {
if ((form.cad_nom.value == &quot;&quot || (isNAN(form.cad_nom.value))){
alert (&quot;Pleaz, ma'am, tell us your name.&quot
form.cad_nom.focus()
return (false)
}
--->
an so on...
why doesné it work?

javascript is case sesative.try this
(isNaN(form.cad_nom.value))){

form is a keyword so I wouldn't use it as a variable name. Try substituting the form variable with another name.

hehe...
my submit: onClick=&quot;verifica(this.form)&quot;
so, I'm not supposed to have trouble with this

onpnt: no error msg with your code, but the numbers went on smooth through the function...

that would indicate that the value of the form is not being passed correctly.
place this in the function to see if you are validating a actual value
alert(form);

HellTel is very correct in form being a keyword and you should change all references to that word as you have it to something like frm. this may be the reason behind this not validating correctly A language that doesn't affect the way you think about programming is not worth knowing.

alert(form.cad_nom.value);
----------->returned the value correctly

and besides, all the other validations are working alright
