Combo Box/Text Box will not save in table

[advlghtcon]

Hello,

I have a main table where I want to store input from a form. My form has employee information such as Name and ID. I have a combo box for the name which works great. I then have a text box with a control source =[Tbl_Emp_Name].column(0) which gets the employee ID to show up. However, I cant figure how to write the text box data(employee id) back to the main table for storage. Any help is appreciated.

Thanks
