4 101 fif 50 0
5 101 six 250 1

If D1 is zero - no action
If D2 is 1 - Copy {B2 to C2) to E1
If D3 is 2 - Copy (B3 to C3) to G1
If D4 is zero - no action
If D5 is 1 - Copy (B5 to C5) to E4
so on and so on

The E column can go up to 14. The marco needs to read to the end of the
spread sheet for last row.

This is short and sweet. I can provide more detail if required.

Thank you
