How do I restrict a comma from a number validation?
Ive got the client Validation toolkit checking a field on my form before submitting it to my credit card processor. I am getting an error back from my processor "Invalid XML" only if the user enters a number in the thousands with a comma.
How would I either strip the comma out, or make the message pop up "Dont put a comma in your number"?
Thanks!

PS: Here's my code...
on the button...
WAValidateNM(document.form1.chargetotal,'- Invalid Amount',1,20000,2,'','',',.',document.form1.chargetotal,0,true);
function...
