Compile error: Method or data member not found

I'm practically bald from pulling my hair out !!

This is a training tracker that is intended to log all employees, the training they've taken and when the next due dates are.
I've used advanced filtering on the data page to help filter the data and set up a user form that is basically non functional. I need to be able to narrow down the field using this user form as well as add additional employees and their training, edit training dates, delete a single training or delete an employee all together.
I keep getting the error in the title whenever I use any of the controls in the user form. I'm sure there are plenty of other errors but I cant seem to get past this one to try out anything else.
Later, I'd like to add a report function but not until I can find out what's wrong with this stupid thing.

Any help is much appreciated!!

(As a side note, this is not a homework assignment)
