i have a spreadsheet with sheets named as follows

St1, St2, St3, St4, St5 etc...

I would like to enter a number into a cell on a separate sheet that will
only show the sheets up to that number and hide the rest.

For example if i enter 3, I would like St1, St2 and St3 to show and the rest
to be hidden.

I am going to use a form to enter the number into the sheet, but for the
moment i need to find code to do the task first.

Can anyone help?
