thanks for coming to my aid, guys. reload the value within the isr. now i know. the timer is working, with the offset with a new problem; im aiming for 3840 hz, and thats = 64233 offset value.
instead, im getting 3030 hz. i used a different pic timer calculator because picmulticalc will not run in windows 7.
this is not really a big problem, as i can adjust the offset value to get the exact frequency that im aiming for.

Timer1 VAR WORD EXT ; what does the EXT stand for?

thanks
