I'd suggest that your stop message tells the user to press Esc to terminate
the process. Use Application.EnableCancelKey = xlErrorHandler (see Help) to
have an error handling macro take over from there.

| Hi,
|
| I have a userform where you input data, then a macro runs through 1000
| scenarios.
| I have another userform that pops up after the main userform - this
displays
| what scenario the macro is on.
|
| My question is: Is it possible to add a "Stop" switch to the userform that

| Thanks for your help
