Pay Grade Population Formula

[Laingy24]

Hi Everyone,

Could you let me know how to rework this formula to better serve me ...

I am currently using this:
=LOOKUP(COUNTIF(J5:FU5,"Completed"),{0,19,48,71,85,95,101,111,130,150,168},{"Starting Grade (£6.31)","Grade 1 (£6.45)","Grade 2 (£6.55)","Grade 3 (£6.75)","Grade 4.1 (£6.95)","Grade 4.2 (£7.25)","Grade 4.3 (£7.45)","Grade 4.4 (£7.55)","Grade 5 (£7.95)","Grade 6 (£8.45)","Grade 7 (£8.95)"})

So if 0-18 occurrences of "Completed" are found within the range then "Starting Grade (£6.31)" is displayed in the cell. If 19-47 occurrences are found then "Grade 1 (£6.45)" is displayed and so on.

I want to update this and change the "Completed" to a choice of multiple words (i.e. January, February, March, April ... December) so if any of these words are found they count as 1 value. So any month would count the same as one "Completed" in the old formula.

You will see at the far right of the screen I have placed my various pay grades that I want to show at each of the increments (i.e. 0-18, 19-47, 48-70, 71-84, 85-94, 95-100, 101-110, 111-129, 130-149, 150-168).

Is this possible?
