Urgent Help needed on 8051..

tmod in timer 2

hey guys... below is my program for displaying the RPM count from the gear tooth sensor mounted on the flywheel of the engine. I am unable to set the register properly for overflow count and also I am not sure if I am getting proper results at the serial display....
I have written this program recently and have to be able to execute on the hardware in 2 weeks from now!... there are no errors as such in the program.
I need ur help urgently!!!!! can you just let me know if the program is right or do i have to make any changes....?????

I also have include PWM using PCA modules... is it possible for me to do that....
this PWM will be control the throttle position by the help of electro-magnetic solenoid valve...I am using timer 2...and im not sure which value to load into the count... should it be RCAP2L or somethings else???

this is the program I am using NXP(philips) make 8051 which has 3 timers and also a PCA module for PWM etc,... plzz help!!!! I will be displaying the RPM serially for every 1 second, but I think even that part by initializing the timer0 interrupt is not working properly..
