I have a table full of values that I want to look up in a table like below (incomplete data set just for iillustration):


[TABLE="width: 96"]
<COLGROUP><COL style="WIDTH: 48pt" span=2 width=64><TBODY>[TR]
[TD="class: xl70, width: 64, bgcolor: transparent"]Aggregate Industry Equivalent Unit Score[/TD]

[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]1.65[/TD]
[TD="bgcolor: transparent, align: right"]1.35[/TD]
[/TR]
</TBODY>[/TABLE]

If the value I am looking up falls in between any of the values in Column A above (Aggregate Industry Equivalent Unit Score), I want it to return the applicable lower value from Column B (Industry Diversity Score) of the two numbers that it falls in between. For example, the results would be:


[TABLE="width: 96"]
<COLGROUP><COL style="WIDTH: 48pt" span=2 width=64><TBODY>[TR]
[TD="class: xl70, width: 64, bgcolor: transparent"]Aggregate Industry Equivalent Unit Score[/TD]
[TD="class: xl70, width: 64, bgcolor: transparent"]Industry Diversity Score[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]0.54[/TD]
[TD="bgcolor: transparent, align: right"]0.5[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]0.26[/TD]
[TD="bgcolor: transparent, align: right"]0.3[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]0.049[/TD]
[TD="bgcolor: transparent, align: right"]0[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]1.061[/TD]
[TD="bgcolor: transparent, align: right"]1.05[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]0.96[/TD]
[TD="bgcolor: transparent, align: right"]1[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]0.275[/TD]
[TD="bgcolor: transparent, align: right"]0.3[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]0.585[/TD]
[TD="bgcolor: transparent, align: right"]0.6[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]1.315[/TD]
[TD="bgcolor: transparent, align: right"]1.15[/TD]
[/TR]
[TR]
[TD="bgcolor: transparent, align: right"]1.315[/TD]
[TD="bgcolor: transparent, align: right"]1.15[/TD]
[/TR]
</TBODY>[/TABLE]

Is there are good formula trick for this?

Thank you.

Hi wpyles,
Yes you can use =VLOOKUP(D2,$A$2:$B$19,2,1)
When the last parameter is set to true (in this case 1) it works like you need/described
Cheers
Sergio
