I am passing a Javascript value from 1 page to another (in lasso language) by using this function below. count is the value I'm passing.

function submitValue(el) {
var elm = document.getElementById(el);
var val = count;
elm.value = val;
return true;

and then sending it in the form on to the next page like this -

<form name="postform" id="postform" method="post" action="action.lasso" >
<input type="hidden" name="param" id="param" value="" />
<input type="submit" value="Submit - Pay by Credit Card" onclick="submitValue('param');" />

I now want to send a second Javascript value (count2) in the same form.
How can I do this? Do I need to set up another function or include it in the same function. And then how do I reference and send the second value in the form?

Thank you for any help
