i think it is the fact that i have a countif formula in column O but not in the others as I put the countif formula in column N and it worked. is there anyway around this. below are the forumlas used in each column:
column n: =IF($F7=$L7,"TRUE",IF($I7=$L7,"TRUE",IF($K7=$L7,"TRUE","FALSE")))
column o: =IF(OR(COUNTIF($L7,$F7&"*"),COUNTIF($L7,$I7&"*"),COUNTIF($L7,$K7&"*")),OR(ISNUMBER(SEARCH({0,1,2,3,4,5,6},$L7))))
column p: =IF(N7="TRUE","FALSE",IF(LEFT(F7,1)=LEFT(L7,1),"FALSE",IF(LEFT(I7,1)=LEFT(L7,1),"FALSE",IF(LEFT(K7,1)=LEFT(L7,1),"FALSE",IF(LEFT(R7,1)=LEFT(L7,1),"TRUE",IF(LEFT(U7,1)=LEFT(L7,1),"TRUE","FALSE"))))))
column q: =IF(LEFT(F7,1)=LEFT(L7,1),"FALSE",IF(LEFT(I7,1)=LEFT(L7,1),"FALSE",IF(LEFT(K7,1)=LEFT(L7,1),"FALSE",IF(LEFT(R7,1)=LEFT(L7,1),"FALSE",IF(LEFT(R7,1)=LEFT(L7,1),"FALSE","TRUE")))))
