Copying contents of specific textboxes from one userform to another

Hi

I am creating a user form for data entry which is all working fine at the moment.

There will eventually be 4 user forms with the data entered by different people; the entry values are limited to 0,1,2,3 and 9 and are entered into a series of textboxes.

Where a 9 appears I want that value to be carried over to the same textbox on the next/all other user forms.

Is this even possible?

Any help appreciated thanks
