Good afternoon RobynC
This code will stop the user from being able to close the form via the X control - just drop it into your userform module
If you prefer, I can supply you with a piece of code that will supress the X from being displayed - a userform without the close button. This trick utilises API's, so is a little trickier to implement (but looks good), but I'll dig it out for you if you (or anyone else) wants it. if you decide to use that, however, you'll still need the code supplied above to stop people crashing out of the form by pressing Ctrl + F4.
