How would I make a loop that increases the speed of a particle emitter every second. I'm not familiar with user data errors and what they mean but I keep getting them with this one line of code.
repeat
ParticleEmitter.Speed = ParticleEmitter.Speed + NumberRange.new(10, 10)
wait(1)
until nil
It's all one line by the way.

Not 100% on what your intent is with the use of NumberRange here, but try just using a primitive (ParticleEmitter.Speed = ParticleEmitter.Speed + 10, for example) to see if that works.
Unfortunately that doesn't work
It gives me the error: Workspace.tygerupercut3.LocalScript.Script:155: attempt to perform arithmetic on field 'Speed' (a userdata value). Which is why I added the number range in the first place. Any other ideas?
