Formating just Created task to update module

Formating just Created task to update module

Hi All,

I am attempting to store the follow-up task ID created below in the Enquiries Module.
When I do info on the Follow_up_task_id it gives me the right Task ID number that was created. But for some reason it is not storing it in the following update : update = zoho.crm.updateRecord("Enquiries",EnquiriesID,{"Follow_Up_Task_ID":Follow_up_task_id});.

I have the feeling it is a simple fix.

Deluge code below
-------------------------------
subject = "Follow up on Enquiry from " + First_Name + " " + Last_Name + " For " + Property_Name;
dueDate = today.addDay(0);
//Create Task Map
tMap = Map();
tMap.put("Owner","42027940000**********");
tMap.put("$se_module","Enquiries");
tMap.put("What_Id",EnquiriesID);
tMap.put("Subject",subject);
tMap.put("Due_Date",dueDate);
tMap.put("Type_of_Task","Listing - Enquiry");
tMap.put("Status","In Progress");
tMap.put("Interest","New");
tMap.Put("Property_Address",Property_Name);
tMap.put("Email_of_Contact_Name",Email);
tMap.put("Mobile_of_Contact_Name",Mobile);
tMap.put("Who_Id",ContID);
createResp2 = zoho.crm.createRecord("Tasks",tMap);
Follow_up_task_id = createResp2.get("id");
update = zoho.crm.updateRecord("Enquiries",EnquiriesID,{"Follow_Up_Task_ID":Follow_up_task_id});
//End Task for Frenchy Follow Up after Inspection
