Basics.......
To protect(lock) any portion of a worksheet, worksheet protection from
Tools>Protection MUST be enabled.
By default all cells are locked when protection is enabled.
You must designate to Excel which cells you want locked or unlocked.
Select all columns you wish to be unlocked(in your case, E through IV) then
Format>Cells>Protection. Remove the checkmark from "locked".
NOW.........you must enable worksheet protection.
A through D will be locked for editing. E through IV will not be locked, so
users can enter data in these columns.
