Can you please tell me what I need to include in a custom field to be able to calc % recovery?

I took the basic course on custom fields but I am trying to figure out what formula I need to put in to calculate % recovery.  Can you please help?

    Percent recovery is a simple calculation and requires 2 custom fields: 

    1. Component custom field for the theoretical amount, ie the amount you spiked the sample with.
    2. Peak custom field which is Amount/Theoretical Amount*100. 

    Where the Amount is the calculated amount from the calibration curve.   This assumes you have no other peak eluting at the time of the peak of interest.
