function undefined error

[BeanNoob]

I'm pretty new to javascript and keep getting this function undefined error. I am trying to pass values into an external javascript file.

I reference the file like so.

Code: Select all

<script src="checkform.js" language="javascript" type="text/javascript">


</script>


In the onsubmit of the form, I call this function:

Code: Select all

function runCheck(){

if (document.c_order.ae.checked)
{
var cardnumber = document.getElementById(cnumber).value;
var cardname = 'ae';
checkCreditCard (cardnumber, cardname);
}

CheckForm();


}


If the above worked I was going to add some more if statements. However, I get the undefined error. Here is the function start in the external.js file:

Code: Select all


function checkCreditCard (cardnumber, cardname) {


The checkCreditCard function is what errors every time...
