Try this,

Build a simple table of category/cost like this


Col D Col E
A 100
B 200
C 300


Then in C2 type this and drag down. Note that my table is in D1-E10 so alter
to suit.
=VLOOKUP(B1,D$1:E$10,2,FALSE)

I have a spreadsheet with three basic columns,

Town Category Cost
Sheffield A £
Bath B £
Manchester A £
Newquay C £
Stamford D £


the category is based on size of the town and are either A, B, C or D.
each category has an equal set cost (e.g A= £100, B= £80, C= £60, D= £40)
I need to know if there is a formula to automatically fill in the cost when
I enter the category in column B? hope this makes sense!
