Combo Boxes in Visual Basic and excel

Hi,

I am currently working on a project at work and am looking to create a user form in visual basic. It will basically have a label saying "Please enter a reason for rejection" and a combo box containing a list of possible rejection reasons.

My list is currently in Excel, and for every reason for rejection, i have a message which at the end of the macro will become part of an email.

I would like to be able to create something so when the the reason for rejection is selected, and the user hits 'ok', the corresponding message will appear in a hidden worksheet which will act as the source for the email.

I have no idea how to link the form from visual basic to excel and even if this is possible? Could anyone point me in the right direction and let me know if this is do-able, and any help on codes etc would be greatly appreciated.

Thanks all
