I see the text string entered, but the formatting says "Number - General".

When I add ;M/Y nothing changes. Or did you mean, that after this change
if I enter 10/2013 into the cell it should be formatted as date? Then
this doesn't work.

Of course my formula is referring to another cell ;-) I changed the
formatting of those cells to Date MM/YYYY and everything works now. I
"only" had to manually remove all those pesky ' from the beginning of
the expression, which appeared after I changed the formatting.
