Trouble reading data from Honeywell Pressure Sensor (24PCEFB6D) with NI-9219 using MATLAB.

I am having trouble reading data from a pressure sensor using MATLAB. The pressure sensor is connected to an NI 9219 Analog Input Device. Firstly, i tested the device to make sure it works using NI DAQmx (Measurement and Automation Explorer) software and it does but when i try to set the same setting in MATLAB I get errors, my code, waveform and workspace is shown below :

The following waveform is produced when lines 14 to 16 are commented out in the figure above:
