lookup formulas dependent upon lookup formulas
 

I dont think I expressed myself clearly.

The initial lookup formula (given below) works well and returns a value in M7.

=LOOKUP(L7,{0,15,15.1,15.4,15.5,15.9,16,16.9,17,17 .9,18,18.9,19,19.9,20,20.9,21,21.9,22,22.9,23,23.9 ,24,24.9,25.0259},{"1.00","1.00","2.50","2.50","4. 00","4.00","5.50","5.50","6.50","6.50","7.00","7.0 0","8.75","8.75","9.50","9.50","10.75","10.75","12 .00","12.00","13.25","13.25","14.50""14.50","15.75 ","15.75"})

The value of M7 could be any of the following

1.00
2.50
4.00
5.50
6.50
7.00
8.75
9.50
10.75
12.00
13.25
14.50
15.75

In O7, I need to look at the value of M7 (being drawn from the lookup
formula looking at the value in L7), and depending which value was returned,
return yet another value eg

1.00 returns £0.00
2.50 returns £1.75
4.00 returns £3.50
5.50 returns £4.50
6.50 returns £5.25
And so on to
15.75 returns £16.00

I have tried to do this by using a similar lookup formula to the first,
however it returns #NA! I dont know if this is because I am doing something
wrong or because it is not possible to perform a lookup formula upon a
previous lookup formula.

lookup formulas dependent upon lookup formulas
 

Where does M7 come into it, do you mean L7?

If you simply want to look at L(M)7 and return values from your tabel then
build a table likes this:-

0 1
2.5 1.75
4 3.5
5.5 4.5
6.5 5
7 5.5
7.5 8
8 16

Note the laft hand side must be sorted and use this formula to look at L7

=VLOOKUP(L7,A20:B27,2,TRUE)

Note that my table is in A20 to B27
