I don't see anything clearly wrong with your script. Does it make a difference if you set a strictly positive lower bound on parameter `p1`, e.g. `lbound=0.0001`?
Running Growth Mixture Model with 15 parameters
Error in runHelper(model, frontendStart, intervals, silent, suppressWarnings, :
Growth Mixture Model.fitfunction: component GMMClass1.fitfunction must be in probability units
If I don't apply the growth mixture part, the three-level model works. So the problem occurs only when i added the GMM part .
Sorry for delay
Hi Caitlin
Sorry to take so long to respond here. I'm not sure why you get this error, but I will escalate the issue with my colleagues.

It still shows after changing
It still shows after changing the lbound=0.0001

Also upper bound p1 at .99999
Hi
Does it help to also give an upper bound to p1 to keep it within the 0-1 range for probabilities?
