Question on Calculation fields

Version 1

    Hello Community - I'm fairly new to Filemaker and am having difficulty and could sure use some help.

     

    scenario eg:

     

    1.      "sug list"   -  "first discount"   *  "freight" = value to automatically go into field "face of invoice"

                 105.74    -        71%             +    10%  =    "face of invoice"

     

    2.      "sug list"   -  "first discount"   -  "2nd discount*  +  "freight" =     value to automatically go into field "Net Cost"

              105.74     -        71%            -           7%            +     10%   =    "Net Cost"

     

    While I have played with this for a couple of hours I seem to be in a loop and can't figure it out except to calculate the final result as 0.00.

     

    Any assistance would be greatly appreciated.
