Using A Single Cell For Data Entry

Basicaly what I am trying to accomplish is the use of a single cell to enter the values 1 thru 60, so starting at e2 for instance, if I enter the number 1 then cell f2 will populate with a 1, if I were to enter the number 18 then the cell w2 would populate with an 18. So the range of cells that need to populate in this example would be (f2:BM2) for row 2. Furthermore if I were to enter a -1 or a -18 in cell e2 then those numbers would be eliminated from the appropriate cells on row 2. The next 299 rows would need to perform the same way for a total of 300 user input rows.

The way that I'm imagining e2 would behave in the example would be...type a 1 then enter....18 then enter....31 then enter and so on. Columns f thru bm would locked and unselectable....so a tab should send me back to a3.

Reasoning.... this is a simple scoring system based on 60 codes and data integrity is very important and I want to eliminate as much human error as possible. I will be setting autofilters and such later on.

I am attaching a screencapture as well.
