Loop through the select elements on the page (which you already have) and check the values. Just .value is usually enough.

wait wait wait...
look at what you guys put... get Element By Tag Names -
alert(document.getElementByTagNames('select').length);
-
where it should be... get Elements By Tag Name -
alert(document.getElementsByTagName('select').length);
-
-
function CLcheck() {
-
var total = 0;
-
var sels = document.getElementsByTagName('select');
-
for (i=0; i<sels.length; i++) {
-
var opts = sels[i].options;
-
for (c=0; c<opts.length; c++) {
-
if (opts[c].value == "CL") { total += 1; }
-
}
-
}
-
alert(total + " Combo boxes had the value CL in its options");
-
}

others are Inactive.
The form shows all the products purchased by a customer, both Active and

I have a combobox that is bound to a dataview generated from a dataset.
The dataset has a single table (called "Data") with two columns "Id" and
"Description". Id contains a code and description contains the

Desired behavior;

the field of the new record.
I have two simple tables. "tblPerson" is the data table. The lookup
