custom field

[medinj01]

Hi,



How can i make a custon field for this formula:



Area Peak1 *100/Area Peak1 + Peak2

[DR]

What you have written will reduce to area peak1 + area peak2.

Shall we assume you meant to ask for
area peak1*100/(area peak1 + area peak2)?

If only peaks 1 and 2 need be considered, name them, do not include any unknown peaks in your integration & calculations and include an area % field in your report. No custom field needed.

the initial formula reduces to:

100 + Peak 2

and whatever formula you want to add the important question is: to which integration system?
