Hello,

I have a sheet that has data such as:

Hr mL gas
0 0
0.05 3.5
0.1 3.5
0.15 3.5
0.19 3.5
0.25 3.5

And another sheet that looks like this:

Hr Action
21 O2 Trap changed
44 O2 Trap changed
69 Computer failure
92 O2 Trap changed
116 Nutrients added
164 O2 Trap changed

I want to add a column to the first sheet called "action" and intergrate the
two tables.

I tried : VLOOKUP(A6,Sheet2!A:B,2,FALSE)...in sheet 1 column C

Problem is that "Hr" in sheet 2 does not necessiarly occur in sheet 1 "hr"

Any suggestion

Thanks

Susan
