Bleutooth servo car

Hello everybody,

I have a little problem with my project at school,
the motor and servo arent operating as I hoped.

when i slide the slider all the way to the left it keeps on going to the left,
when i slide it to the right it goes to the left for 0.5sec en then slow to the right

the 2 motors arent responding at all...

i'm new to the arduino programming so that's why i am asking you guys to help me
*sorry for bad english im from holland (Netherlands)

Here is the code:
