# Excel - IF Function Problem - Expert Solution

Question description:
This user has given permission to use the problem statement for this blog.

I'm trying to write a formula that would find the percentage of Customer Invoices that have stayed in the same Row rank (Column J) for 2 consistent months. The rankings are segmented based on the criteria in Column P. The sheet I'm working on is labeled Top X and the formula should be inputted in Q200:AZ212. The Row rank is found in column J, the Account ID is column B, and the Date range is in C (note the date range is Text, but the corresponding Dates needed for segmenting the data are located in Q2:AZ2. Please let me know if you have any questions!

Top X

So column Q should be blank right? I'm thinking that the 2 months you want to identify is the current month and the month before.
Excelchat Expert 14/08/2018 - 05:49
So 201601 needs a 201512 as well.
User 14/08/2018 - 05:50
It's fine if we don't get the first month. We don't have the data
Excelchat Expert 14/08/2018 - 05:50
Okay.
Excelchat Expert 14/08/2018 - 06:13

So the formula is checking how many customers are between a certain range, 1-10 to 11-20 for example, for two consecutive months, the current month and the previous one.
Excelchat Expert 14/08/2018 - 06:15
The formula is in R200:AZ212
