Excel - populating data (checkboxes) based on combo box selection

Hi Leith,
I noticed you helped out an individual on this forum (similar to what I am currently struggling with), so I thought you would be a lifesaver!

I'm creating an Excel 'form' where the combo box values are a list of countries (approximately 75). Based on selection, the cells to the right would populate all "responsibilities" associated with that country. As mentioned above, I found a similar example, however, what I'm having trouble with now is adding additional countries and adding additional lines/responsibilities with checkboxes. Each time I try to add a new line to the list, I'm getting an error. Please help! I've spent hours and I'm not getting anywhere...

Hi gkang116 and welcome to the forum. Please amend your title as per rule #1 of the forum rules located here. Once you do that, someone (Leith) will be able to help you.

Hello Grace,

@ Mordred - Thanks for pointing out the rule. The OP contacted via PM. Because this a first post, I wanted to see the workbook to help suggested a proper name for the thread.

Is this the post you are referring to http://www.excelforum.com/excel-prog...a-library.html? Do you want to use a similar setup with your UserForm?

Hello Grace,

That was a novel idea. I can make the needed changes to your workbook so it does the same thing.

Hello Grace,

You did a great job converting the code to your workbook. It works fine. To expand the Project lists, simply click on the last cell in the list. A new row will appear with an asterisk "*". Type the new information in and repeat. Everything else is adjusted automatically.
