Validating multiple field options in Zoho form.

Validating multiple field options in Zoho form.

Hello,

I was hoping someone could help me out with this, I am still very new at coding, and the only validation script for a pull down menu with multiple fields I can get to work is the following. However, when I use this, it transfers the option number into Zoho instead of the actual field name I want:

function validateForm(objForm)
{
    var returnStatus = 1;

    if (objForm.Make.selectedIndex == 0) {
        alert("Please select a Service Level");
        returnStatus = 0;
    };

    if (returnStatus) {
        objForm.submit();
    }
}
<SELECT NAME="Make">
    <OPTION VALUE="0" SELECTED>None</OPTION>
    <OPTION VALUE="1">Bronze</OPTION>
    <OPTION VALUE="2">Gold</OPTION>
    <OPTION VALUE="3">Trial</OPTION>
   
</SELECT>   

Can someone please explain what I need to do to make this required and have the appropriate value transfer into Zoho CRM instead of just the number?  As I said, I am new so please try to explain clearly.
