Populate Input box with result from Selection

[jon24422531]

Guys

Not sure if this is a bit of a newbie question, but here goes:

I have a form in which users (it's an internal web site) report on our customers. This form has a selection drop down box that I have populated with our unique CustomerID. What I would like is for another Text Box to be populated with that customers Name depending on which CustomerID is selected. The SQL part is OK, and I can return all the data, but I am not sure how to dynamically update one field with the results of another.

Any help would be much appreciated.

<script type="text/javascript">

function changeme(me)

{
var doItToME;
var model;
var amtx;
doItToMe = window.document.getElementById("amt");
model = me.value;

if (model == "T30")
{
amtx = "400.00";
}


amtz = parseInt(amtx);
amtx = amtz

if (amtz > 0)
{
amtz = amtz+ 25;
amtx = "$" + amtz + ".00";
}

doItToMe.value = amtx;



}

</script>
.
.
. this format is based on a pull-down (select) that selects a model.
. another box (amt) is filled with the value based on the select
. the example above will fill $400.00 in the amt box if the selected model is T30.

<SELECT NAME="modl" id="modl" SIZE="1" onchange="return changeme(this)">
