Acorn999 Try using this validation formula:

=OR(ISBLANK(MEMBERMBI),LEN(MEMBERMBI)=11)

Note: Sometimes comma(,) does not work in formula (it is based on language or regional settings on your site). So in that case use semicolon(;) instead of comma(,)

This resolved the issue. Very appreciated. Also the formula is entered in "column validation" and it works there. If I now go to "list validation" the same formula shows there. Next time for any issue, I will try entering the formula in both places and also try replace comma with semicolon.
