Thread: Merge cells automatically

Hi All,
I have a requirement. I have attached a sheet where i want to merge cells automatically based on a condition.
Column B is the name field and A is the Id field.
Column D shows the target achieved which contains three values Y,N,NA
Column E shows the overall achievement.
the logic to merge the cells is ,for a particular name and particular month when the target achieved is Y or NA then achievement is Y and the cells should be merged.
for a particular name and particular month, when any of target achieved is N then overall achievement is N and the cells should be merged.
Please help me to solve this issue
