I have a dead line to meet so sorry for the rush

I need help with the following spreadsheet.

It is to report On Time Delivery. I have set up as much as I can but to be honest I need help on the formula in column " G ".
The report is based on deliverys on the same day mostly within a 12 hour period.

This is what I am hoping to achieve/

1) If the time in column D is prior to the ETA but not prior to the ship time show in cell G2 as " On Time "

2) If the time in column D is prior to the ETA and prior to the ship time show in cell G2 as " Early "

3) If the time in column D is after the ETA show in cell G2 as " Late "

4) Regardless of what time is entered in column D, if a letter ( A, B, C etc. ) shows in column F show in cell G2 as " On Time "

The letters are used when a delivery will technically be late due but due to a reason such as customer NSF.

The first cell to paste the formula in should be G2


Any help would be appreciated.
