Modify userform textbox data validation to include text instead of just integers

Hi all,

I found some VBA code that allows viewing/editing cell values that are linked to textboxes in a userform. The cell values are displayed in multiple userform textboxes based on an integer. Example, when a user inputs an integer that is valid, a corresponding set of textboxes are populated with data unique to that integer. What I want to accomplish is to allow a user to choose a string value from a combo box on the userform that will then populate the textboxes in the userform with the corresponding data values from the spreadsheet. I've attached the code.

Thanks!
