Ron,

This formula isn't working......I Can't get it to work using Alt+Shift+Enter
or by just using enter. Can you help? Please

OK...I understand.....
You want to search a particular test for a certain value.
If that exact value is found, then return the associated top row value.
If that exact value is not found, then you want to interpolate the top
row values.

Again...using your posted data list in A1:F4

and
A8: (Test to use....eg 2)
A9: (value to find...eg 1.5)

Try this ARRAY FORMULA, committed with CTRL+SHIFT+ENTER, instead of just
ENTER:
A10: =INDEX(A1:F1,MATCH(A9,OFFSET(A1:F1,MATCH(A8,A2:A4, 0),),-1))-
(INDEX(OFFSET(B1:F1,MATCH(A8,A2:A4,0),),MATCH(A9,O FFSET(B1:F1,
MATCH(A8,A2:A4,0),),-1))-A9)/SUM(OFFSET(INDEX(B3:F3,MATCH(A9,
OFFSET(B1:F1,MATCH(A8,A2:A4,0),),-1)),,,1,2)*{1,-1})

Does that help?

it does help but if it isn't an exact match I still need it to return a
value. between the two numbers. ie: if it's between 98 and 99 I need it
to
mathmatically calculate if it would be 98.something......

For an exact match...

Try this:
A8: (Test to use....eg 2)
A9: (value to find...eg 1.5)

This formula returns the top row score
associated with the A9 score
for the A8 test.
=INDEX(A1:F1,MATCH(A9,OFFSET(A1:F1,MATCH(A8,A2:A4, 0),),0))

NOTE: if the A9 value is not found....the formula returns an error.

Does that help?
Post back if you have more questions.

I am looking for either a macro or a function that will return a certain
value.
ie: % With in Limits
test 100 99 98 97 96 .......
1 0.9 0.8 0.6 0.3 0.1
2 1.8 1.7 1.5 1.3 1.0
3 2.9 2.8 2.4 2.2 2.1

Test #2 find number 1.5 Return value 98

I hope someone can help me.
