The Custom tool has no number outputs, only images, so it's not suitable for this. What you want is the Probe Modifier. Right-click on any number control & choose Modify With -> Probe. You can then connect any image tool to the Probe, select a region to look at, choose Channel and Average/Min/Max etc, and the pixel values will drive the number control. --Daniel
