Using a command button to move text between two controls!

Can anyone offer advice on how I can program a command button using SQL so that the 'On-click' event will move text from an unbound edit box on one form to a separate bound edit box on a different form?

I'm looking to be able to select just one comment from a range of six comments, each comment is presented in a seperate edit box control, with all the controls on one subform there are also 6 comments per subject, with a total of approximately 15 subjects. Making a total of about 90 potential comments. The selected comment will then be reviewed and inserted on to the data capture form once it has been placed in to the edit box control.

Any help would be appreciated
