paramsMap = Map();

paramsMap.put("Title",input.Title); // this is working

PriceList = List:Map();

for each  rec in input.Prices

{

PriceMap = Map();

PriceMap.put("Item","Test"); // Item = column/field in CRM

PriceList.add(PriceMap);

}

paramsMap.put("Items",PriceList); // Items is the name of the subform field in CRM

respy = zoho.crm.updateRecord("Test_Module",input.CRM_ID.toLong(),paramsMap);

The "Title" is updated, but it is not working for every line in the subform.
What's wrong or missing?
