Cell J14 contains the value to be tested
Create a table in cells C1 to D6 as follows:
2 18 coaching
3 24 verbal
4 30 written
5 36 90Day
6 39 termination
In cell K14 enter this formula:
The text requested will show in cell K14.
You can of course have the table anywhere, even in a different worksheet, just make sure
the formula points to it, e.g., =VLOOKUP(J14,Sheet3!$C$1:$D$6,2)
If you prefer nested IFs then use this:
The VLOOKUP() version is better if you are going to use this formula in more than one place,
then if you need to change the break-points or the text, you only have to make
one change (in the table), rather than changing every formula.
