Thanks for the information...I solved the problem!
I did what you suggested and moved the Motor_1.runSpeed() and Motor_2.runSpeed() to the end of the loop, changed the Motor Stop commands to "b" & "e" and added the following lines to the Motor Stop command...If (BluetoothData=='b') { Motor_1.setSpeed(0); Motor_1.stop() }.
Did this for both motors and now everything works as planned.
Thanks again,
