Pushkardey and Marcelo Branco,
I used your formulas,
=IF((MOD(A1+C1+E1+G1,2)&MOD(B1+D1+F1,2))="01",1,"")
=IF(AND(MOD(A1+C1+E1+G1,2)=0,MOD(B1+D1+F1,2)=1),1,"")
and they worked with my test file but when I enter them in my real file they wouldn't give me the right result ??? why is that ?
My actual cells range are : AG6:AM6 up to row 600.
Sorry about the late reply,I had to leave and I just got back !!
The only formula that worked perfectly is the 2nd one in Mikerickson's post.
I change a bit the range of his formula to adapt to mine and scroll down to all my data and the result is perfect.
I need to change the formula to work for different criteria for example :
1) OEOEOEO
2) EEEEEEE
3) OOOOOOO
4) EEEOOOO
Etc..
I tried to fix it but I couldn't figure it out how, can someone explain what need to be change in the formula to make it happen for the example above ? and then I'll be able to do the other one.
Thanks for the help.
Serge.
