Macro to sort

[beth804]

I hope this is easier to understand and that this is posted in the right place.

Cells: C6 to T61, that's the 6-row from the C-column to th T-column. Then down to 61-row.

Trying to sort, ascending, by the I-column, starting at cell I6. I had a macro that worked fine and then for some reason messed up. It is now only sorting from C6 to P61. Completely ignoring columns Q, R, S and T - even though they were included when I recorded the macro.

For example:

Before sort: - in this example sorting by the second column.
a 12 b c
d 03 e f
g 11 h i

After sort:
d 03 b c
g 11 e f
a 12 h i

Notice that rows 3 & 4 have not changed.

My question is why is it doing that and how can I fix it?
