Forms :: Using Combo Box To Populate A Field From Memo Source?

I am programming a database for a reorganized group in my office. For whatever reason they want their correspondence letters within the Database instead of in Word templates. This way I can standardize their headings and automatically import data from their tables onto their letters.

For this reason I chose a form. I felt using a report wouldn't give them enough editing power. Almost all of the fields on this form are unbound and set to default values. I want to use a combo box so the worker can select the "letter type" they want from the drop down and it will automatically update the body of the letter with the standard format of that type of letter.

Just one problem--these letters are wordy, so the "content" field had to be a memo. I know you can't set memo fields to combo box columns, so I'm in a jam.

how I could populate this memo field into the unbound field using some kind of selector? It doesn't necessarily have to be a combo box.

I want to populate the memo field into the unbound box, but I don't want it to establish a link or control source because I don't want the worker modifying the original record (think of it as a template).
