i have a control list in a form that display the results of a search, when i click in one of the results and press a button i want to transfer the clicked result to another form's combo box,  i try to simple set the unique id of the control list into the combo as form!combo = result_list, the bound field on the combo box and the result list are the same but when i click the button i build to run the code an error appear saying that the result_list = unique ID, which is the right result but i do not know why it does not set the combo box of the other form to that unique ID value.
