A lot of thanks for this help Sir!

I have 4 issues...

1. The Table should NOT be dependent on the References Chart, that is, if I delete the Reference Chart completely, still the code should work. (Actually, It does not work when I delete the Reference Chart).

2. If I delete the Alpha Code from a cell (for example C3), the corresponding range (D3:F3) should be empty/deleted automatically.

3. (Similar to point 2 but in reverse order) If I delete any one cell value from the range (for example D3:F3), the corresponding Alpha Code (C3) should be deleted automatically. It means, the Alpha Code should be appear only if all the three cells in the corresponding range (for example D3:F3) are filled. Otherwise, the Alpha Code should be disappear/deleted.

4. If I enter "a" instead of "A" in the Alpha Code, the code should still work. (Actually, it does not work with small letters, only work with caps lock on)
