Timer Triggered ADC Not Functioning

Other Parts Discussed in Thread: EK-TM4C123GXL

Hi,

I'm using a Tiva EK-TM4C123GXL and I can't seem to get the ADC to be triggered by the timer. I've placed a breakpoint in my ADC0IntHandler, but it never seems to make it there. The code is below. I have put ADC0IntHandler in the proper location in the startup file. Any help would be much appreciated. The code is below. 

Thanks,

Kyle
