Use checkbox to show/hide sheets?

Hey

Im having a small problem that im trying to solve in some way. I only have some knownledge in basic macros and not in VBA, and since i cant figure out a way to solve my problem.

Is it possible to do this.

I have a workbook (i attach a testfile). Right now i have 4 sheets in it. The "Main Sheet" is called "Pre"

Here i have 3 checkboxes.

I also have 3 "hidden" sheets called "sheet1", "sheet2" and "sheet3".

What im trying to do is when i "mark" the checkbox called "sheet1" then i want the hidden "sheet1" to show up. And same goes with all the sheets.

So basicly when i click "sheet1" checkbox that sheet will get unhidden.
