Hi

I have a work sheet as below:

Column1 Column2 Column3 Colum4 Column5 Column6
row1 C Y C C_c2 C_c3
END
row2 C N END

For each row in the worksheet, I have to check the Column2,
if the value is "Y",
then I will need to insert 3 columns to the worksheet,
for example, initially row1 is C N END,(three columns only)
After I change the column2 to Y and run the macro, it should change to
C, Y, C, C_c2, C_c3 END.(Six columns)

Similary, for every row, if I change the Column2 value from "Y" to
"N", It should delete next 3 columns after column2.
For example, Initially row1 is C Y C C_c2 C_c3 END,
If i change the Y to N, It should become C N END

Can I get some help to write the excel macro for this?
Thanks in advance!

regards,
Kai
