I spoke recently with someone named expert 12 who was going to bring in a VBA expert to help. Here is a sample of the spreadsheet. What I need this to do is tell excel that when a number is identical in the C column to go to the S column, find the number in S for that duplicate group of C and make all the numbers in S for the duplicate group of C the same as the number found in S. you can see that C3, C4, and C5 have the same number so S3, S4, and S5 are the same number. If you look at C46, C47, C48, C49, C50 and C51 then look at the S column for the same rows I would need it to put the number found in S48 and S49 into S46, S47, S50 and S51. I would then need to find the next duplicate group of C and do the same thing. Finally Column T needs to repeat the same process as S. A mess I know
