What I want to achieve:
1. Accept two filenames from user and store the filenames in two variables (FILE1 and FILE2)
2. Check if files exisits. If doesn't, then exit
3. If files exist, look for a particular string in both files
4. If the string exists, then change the filenames (FILE1 and FILE2) to the string that was looked up in the #3
5. If string does not exist, then do nothing
6. Build up another filename (FILE3) which is some combination of FILE1 and FILE2
Here's the code that I have written. Everything else works fine EXCEPT for point # 4. The variable substitution just doesn't work. I've tried many modifications, and this is the last one which still doesn't work.
The outputs:
1. When the string exists in the file:
Like I said, I have tried many combinations, but nothing seems to be working right. THe variable substitution works well when I do it outside the if loop. but within the if loop, it just doesn't work.

Been breaking my head since yesterday on what is going wrong with a simple substitution, but unfortunately can't seem to get it. Help from you geeks will be greatly appreciated.
