need help with excell funtion
 

Hi,

I have 2 worksheets.

When I type 150 in worksheet #1, I want excell to lookup the value from
worksheet #2 that correspond to 150 (and return those values in Worksheet
#1). Since there is no 150 (in worksheet #2), I want it to give the
corresponding value in column B and C by averaging (In this case the answer
needs to be 15 and 47.5 respectively in column B and C) or if I enter 175
then it should give me 17.5 and 53.75.

Thanks very much for your help.

Worksheet #2

100 10 30
200 20 60
300 30 90

You'll have to say what algorithm you're wanting to use to interpolate
(since you obviously don't want to simply average.

15 would indicate a linear interpolation for column B with an entry of
150, but a linear interpolation of column C would be 45, not 47.5.

Likewise a linear interpolation of column C for an entry of 175 would be
52.5, not 53.75.

JE,

How do you use the interpolate function in excell?

Thx

There is no interpolate function in XL, though if you have two points,
you can use TREND(). I commented because I couldn't understand how you
got your sample results - they weren't straight linear interpolation.
