Print your code line by line
I mean like this:

Line 1 bla bla bla
print("#1");
Next Line bla. Bla bla
print("#2");

And see in consol that which line stops your code (debuging > search in wiki )
If you couldn't fix, post here and tell me which line stops your code…
For example if in consol you see:
#1
#2
#3

This mean after print("#3"); your code stops and copy line after print("#3);

But i think your problem is GetPlayerLastVehicleID
I'm not sure but i think..
I'm on my cellphone and i can't test the code. Debug it by yourself and poat here result
