Help using serial data to control a stepper motor

I apologize for taking your time I should have just stuck with it a little longer. I had commented out the code to the point where it worked again but if I had included those portions I was getting nothing. I have it currently working I couldn't say where the problem lied. Off to find another.....

I was hoping that limiting the floating size would make the function work, thinking it was a limitation of the esp32 chip. I corrected it to elminate the ", 3".
