Populate the selected data from sub form to drop down list

[albert_leung]

I have attached the screen shot for your reference.

We populate the checked out items' call number by using SQL in combobox already. However, users do not want to pick it from the combobox, they want to select the item on the sub form, which is the checked out record, and populate the call number on the combobox automatically. That's what I need help.

Hi albert,

What is the point of this? What is the combo box used for?
