Hello smeader693, welcome to the board.
I'm a little confused by your question.
When you say you have a userform, do you mean you're using an actual UserForm, or are you referring to a form on the worksheet itself for the user to enter data into?
(If you mean an actual UserForm then I'm not sure what you mean by:
"a userform with 10 rows.").
As for loading the ComboBoxes, it sounds like the choices will not only all be the same, but
may be coming from a fixed list. (yes?) If so, then is there a reason you can't just use the
Input range (Forms ComboBox) or the ListFill property (Controls Toolbox ComboBox) to
load them up?
If you're using an actual UserForm, how are you populating the ComboBox(es) now?
