verififing if entry was a number

[tuam1234]

i would appreciate any help.

in the code below, i am verifying if the user entered in a credit card number in the field.

if (document.formname.cardNum.value == "&quot

{
// tell client that you need the name
alert("Please enter a valid card number&quot
// send the cursor to the fullname field
document.formname.cardNum.focus()
// field is empty, so return false to abort the form
// submission
// the client is returned to the form
return false
}


i am trying to get it to check and see if this entry was a number using this statement

(Not(IsNumeric(document.formname.cardNum.value)))

why is it not possible for me to join these 2 conditions together like

if ((document.formname.cardNum.value == "&quotor Not(IsNumeric(document.formname.cardNum.value))))

any suggestions greatly appreciated!!!

Aren't you mixing JScript and VBScript ?
