Multiple channel ADC

Hi, I'm working on the msp430f2274 and I need help regarding multiple analog channels. I'm using channels A0,A1,A2,A3,A4 and DTC to store the value in an array. But the values of each channel doesn't store in the array[#] correctly. For example in my code, value at A0 is suppose to be at samples[4], but it will appear on other samples[#] . There's a picture at the end to show what I meant. From the picture at the end. The top shows value(200+) of channel A0 on samples[4], then the next moment(bottom pic) shows value(200+) of channel A0 at samples[3].
