I am trying to create a record in a form using 'add record' task. However, I am not allowed to insert values in the 'subform' in main form. Also, when I try to update the record to update 'subform' values, it doesn't allow me to do so. I get this error:

Error at line number : 47 
Field 'Calkain_Brokers1' is of type subform and is not supported in update expression

Is there any alternate solution available to achieve this?
