Hi,

I have the following formula in cell K1

=LEFT(ADDRESS(ROW($AA1),COLUMN($AA1)+(COLUMNS($K1:K1)-1),4),2)

I need to copy & past this formula 6 rows to the right each time (i.e. Q1, W1, AC1 etc)

And return the following sequence in the cells;
K1 - AA
Q1 - AB
W1 - AC
AC1 - AD

The formula above is not quite achieving the desired result (currently returns AA, AG, AM, AO in the cells above)

Can someone please help to correct this problem ?

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.
