[Evan Robinson] "Applying wiggle- position or the expression wiggle(1,000) makes a normal layer wiggle"
This will not produce a wiggle since the wiggle amount is 0.
Here is a CS5 file demonstrating that wiggle(1,000) produces no movement on a Solid layer and that wiggle(5,10) produces movement on a Null Object.
