Creating a contact from partner details

So I've got a custom contact page that lists the main contact details down the left and the partner details down the right.

I want to make a script and attach it to a button that will create a new contact and map all the information from partner fields to the new contact record.

The below script is not working for me , but if anyone can help me debug this I would greatly appreciate it

This is the script :

contactId=input.cntId.toString()

rec = zoho.crm.create("Contacts");

resp = zoho.crm.getRelatedRecords("Contacts",cntId);

for each ele in resp

{

mp=map();

mp.put("First Name",rec.get("Partner First Name"));

mp.put("Last Name",rec.get("Partner Last Name"));

mp.put("Mobile",rec.get("Partner Mobile"));

mp.put("Email",rec.get("Partner Email"));

mp.put("Date of Birth",rec.get("Partner Date of Birth"));

mp.put("Smoker",rec.get("Partner Smoker"));

mp.put("PPS Number",rec.get("Partner PPS Number"));

mp.put("Address 1",rec.get("Partner Address 1"));

mp.put("Address 2",rec.get("Partner Address 2"));

mp.put("City",rec.get("Partner City"));

mp.put("County",rec.get("Partner County"));

mp.put("Eir Code",rec.get("Partner Eir Code"));

mp.put("Country",rec.get("Partner Country"));

contactId=ele.get("CONTACTID");

updateResp = zoho.crm.updateRecord("Contacts",contactId,mp);

}
