4GL Calculate Fields

SOLVED

I am trying to do a simple calculation where I need to multiply two fields and the total is displayed in another field. I believe this can be easily done through 4GL programming, but have some questions. My thinking is I would add an action to the screen/field I want to display the result. 

  • What "Action" type would work best if I want this to run on save of the transaction? 
  • Would something like this work for the script  [M:YITMS]YCSETIR * [M:YITMS]YCSETIRPAL

Any help or examples would be appreciated. 

Thanks!
