debug my C program based on my MIPS

Hi i need some one to help me debug my c program. this is the program for stopwatch with the format of M:SS i have to control my interrupt with switch sw1 and sw2 in pic32 so sw1 enable/disable timer and sw2 reset and it has proirity over sw1. i wrote my ISR in MIPS and i am calling them only in c so my c should be simple but the thing is that i wrote both program but my switches doesnt work so when i comment out my if/else statement in c for switches and run program it run as a timer just fine but when i uncomment switch it doesnt work and it just show 0:00. why ??? can you help me and here is my c:
and just to note the template of this progranm was written i just worked on my while loop at the end thats wehre to look
