current.variable.u_currentcy_code="AED"

current.variable.u_currentcy_code.getDisplayValue()=null

I checked code and it has been added via client script as per client requirement.

Now I have to do some calculation based on the display value of the variables. Backend value isa same for both choice. How to get the value because in question_answer table it is just showing backend value. I need to do some DOM manipulation to get this value?

Client script

if (natureofrequest == "new_supplier" && syst == "vendor") {
g_form.addOption("currency_code", "aed_vendor", "AED-Dirham");}
else if (natureofrequest == "existing_supplier" && syst == "vendor") {
g_form.addOption("currency_code", "aed_vendor", "AED-United Arab Emirates Dirham");}

when you use addOption() you need to pass the correct choice value and choice label
