Read ADC conversion sequence with DMA and Timer1 on CC2530

I am trying to read 6 sensor values from the ADC at specific time intervals using compare mode on Timer 1 channel 0 along with the DMA on a CC2530. My current code is below. Unfortunately, the ADC values appear to be gibberish, mostly FF and 00.

I have previously tested the ADC using code without the DMA so I know the sensors are working correctly. I also know that the DMA is working properly because I tested it by moving values from one place in memory to another. I am at a loss as to what is wrong with this code. I am assuming it must be something with the setup of the ADC, but I have looked through the user guide and can't figure it out. In addition I have compared the code to this (http://e2e.ti.com/support/low_power_rf/f/156/t/143710.aspx#520330) which runs on the CC1110 and the only thing I am doing differently is using timer 1 to trigger the ADC. ( I have tested using her settings for the ADC with still no luck) Any ideas as to what is wrong?

Thanks for any help,

Katie
