I can 
create a new formula with your 2 lines below, and using the fml() 
function can call the output from my formula... that all works perfectly! 
Thankyou very much for your assistance.

<FONT

one can use to call the output?

  onlyMikeThe problem of suppressing zero's on 
  the left side of he chart is easy toovercome. Name your output 
  variable  then add the following lines to createan output 
  plotX:=ValueWhen(1,"Plot Name">0,"Plot Name");X;The 
  other issue is not a biggie either.Create a reverse bar count and then 
  use that count being equal or less thanthe specified lookback periods to 
  create a window at the right side of thechart. Then all you do is use the 
  same approach as above (using Valuewhen)to trigger the output when the 
  window is 
  open.B:=LastValue(Cum(1))-Cum(1);X:=ValueWhen(1,B<=HighDays,"Plot 
  Name");X;Roy----- Original Message ----- From: "Mike
