Asigning value to text box if used

I'm trying to make an ordering page where my clients would enter in a image code "L5648"

If a code was entered into a form text box, it would save the image code value as well assign a new value of $6.00 so further down the page, the form would calculate the order total.

So. if 4 image codes were entered I would have 4 values of "6.00" each.

Is this possible?

(See the "Unaltered images burned to cd")

Thanks in advance.
Dave.

Site is in test mode so play if you would like.

Not with HTML. HTML is a static language. You would need a server-side scripting language. Might look into installing an eCommerce package which has an "Add to Cart" function. Alternative is to check PayPal and see what they provide for a Cart function on a web site.

Welcome to the forums, Dave. Major_Payne speaks the truth!

I`m not sure he`s asking about a cart option, but rather a way for the form to total itself up automatically before the pay button is clicked?

Look into javascript/ajax.

I've been working on some code someone gave me on another forum but can't quite get it.

I think I'm having a problem striping out the first letter in the "cd" box.

var re = substr("cd"+c, -4);

The boxes will be populated with image codes like: L5487, S5487, D5487 and T6542.

Sorry if this should be in the java section, I started out with thinking it was a html format problem.

<html>
<head>
<script type="text/javascript">
function getCdCost( )
{
 var re = substr("cd"+c, -4);
 var form = document.selectionForm;
 var count = 0;
 for ( var c = 1; c < 9999; ++c )
 {
 var fld = form.elements["cd"+c];
 if ( fld == null ) break; // out of loop when no more
 var val = fld.value.replace(/\s/g,""); // zap spaces
 if ( val != "" )
 {
  if ( re.test( val ) ) ++count;
 } else {
  alert( "Invalid L number: " + fld.value );
 }
 }
 var cost = 0;
 if ( count > 0 ) cost = 23 + 6 * ( count - 1 );
}
</script>
</head>

<input type="text" name="cd1" size="3" maxlength="5" onchange="getCdCost();this.form.SUBMIT.focus();"><br/>
