STeven,

Thanks...didn't realize that I needed to use GetVariable for created variables.

if minY < GetVariable("Displacement") then

Allen,

Its probably more like:

if GetVariable("SCRIPT_COUNT") = 0 then
SetVariable "Displacement", 10000
end if
minY = GetVariable("MIN_Y")
if minY < GetVariable("Displacement") then
SetVariable "Displacement", minY
end if

basically you where missing the GetVariable on the Displacement since that value would always be zero and second, if you want the minimum Y you need to initialize that to a high number first.

Keeping Track of a Maximum Value

I am looping a video and trying to determine the maximum displacement of an oscillating part. The problem I'm having is that the displacement calculation just ends being the same as teh MIN_Y value. See VBScript below. I have attached the program, but not the video clip.

if GetVariable("SCRIPT_COUNT") = 0 then
SetVariable "Displacement", 0
end if
minY = GetVariable("MIN_Y")
if minY > Displacement then
SetVariable "Displacement", minY
end if
