Conditional formatting

Hi, I've formatted four cells to turn red or green which works fine - if the two crosses match they turn green and if the two ticks match they turn green, otherwise I get red cells.

Trouble is, if I then remove the $ reference from the conditional format formula (just the column reference so that I can copy the section of the spread sheet to a new location directly below), the conditional formatting goes awry :-

Can anyone help me please? I really don't see what I'm doing wrong.

Kind regards,

Mike.
