Hi Guys, 

if we delete values in multiselect lookup field  then automatilly it should delete in sub-form.  Below i have attached pdf .

Now in  Item List field i have added multi select lookup of Fruits_Name and if we select  Fruits_Name in item list those will be shown in sub-form . 

Now my Question is if we delete Fruits_Name in Item_list it must also be deleted in sub-form. How to delete fruits_name in subform   ., can anyone help in finding the solution
