Not enough info for me at least, to help you get what you originally wanted. Post what you tried, and be specific about what these names are (you seem to have 3 or 4 controls in each piece but I have no idea what they are or are supposed to reflect). More info needed about your combo box. Is it bound? What's the row source? Does it have more than one column? Be clear about what you have and what you want to achieve.
Afterthought: Nothing wrong with what you have if it works. Sometimes you just have enough difference between similar events for different controls that you just do it the way you have it. To combine them in a way and still have separate checkboxes would require a separate procedure. If you had one checkbox (yes for cash no for finance) that would be a different story.
The more we hear silence, the more we begin to think about our value in this universe.
