Hello,

I want to store a 12 digit number in a some cells. Ideally, I'd like it with
a space after every 4th number and such that when I copy and paste to other
applications there is no space in between. I tried doing a custom format
set to "#### #### #### ####" but had some serious problems with that.
Firstly, the last number for some reason would change itself to '0' and
another problem I had was that pasting the number would maintain the spaces
even though it was only there in the formating and not in the way the number
was stored.

Can anyone give me some guidance on this.
Thanks you very much.
