List Boxes

Hello,

Trying to revise a series of forms to include drop down lists for applicable accounting fields. Our employees need to select an applicable account and program code for purchases.

I have a attached a draft file if anyone can assist.

The last 2 columns on the Purchase log are where I'd like to have the drop downs, and the lists for the Account and Program Codes are on the 2 separate tabs.

I have tried inserting the list box from the developer tab etc., but not getting anywhere. I guess I'm not sure what's involved and if this may be over my head.

I enjoy teaching myself, so any help is appreciated.

Thanks for any help.
