Define a join in Webi Report which gets the data from two Excel files

Question

Hello,
I have the following excel records as a source for my Webi Report:
Excel 1
Excel 2
Date
Month
Month
Year
Year
Total Number of Days
  in Month
No. Of Exec
Functional
  Area
Now I need to show No. of executions/Total Number of Days in Month per functional area (Where Month of Excel 1 is Month of Excel 2).
For this:
I have Merged, Month of Excel 1 and Month of Excel 2,     Year of Excel 1 and Year of Excel 2.
Created a variable vNoofExec , No. of Exec/Total Number of Days in Month.
Created a graph, with Merged Month, Merged Year, vNoofExec with Region Color on 'Functional Area'.
But, it doesn't work.
If I replace vNoofExec with No. Of Exec I get the data, but not with vNoofExec.
Any Idea how we can get a solution for this?
Best regards,
Praveen.

Hi Amit,
Thank you for your reply.
I tried putting them in a table to see if I am getting the value for vNoofExec but, no, I am not getting. Here is the dummy data for both the excels:
1. Excel 1:
Year
Month
Week
Date
No. Of Exec
Functional Area
2013
1
30
26
1
FA1
2013
2
21
20
12
FA2
2013
3
21
21
1
FA3
2013
4
21
22
5
FA4
2013
5
21
23
2
FA5
2. Excel 2:
Year
Month
TotalDays
2013
1
31
2013
2
28
2013
3
31
2013
4
30
2013
5
31
What I found is, if I create a measure like, [No. of Exec] where ([Functional Area]="FA1") and use this measure in the graph I am able to see the data even if I use Total Days in the Graph, but, I cannot create multiple measures like this because for me number of Functional Areas will be changing always.
