error in multiple channel data generation using NI 9263

[jkfgdbkfjj]

hello there

                      i wanted to generate pwm signal using NI 9263 voltage output module. it works properly when it is generating only one signal but i want to generate 4 signal simultaneously with different duty cycle.i have written a simple programme to generate only two signal but it is not giving me output. although it is not showing any error in programme and it runs contineously but there is no wave form on oscilloscope.

                     i have attached screen shot of my programme and configuration that i have selected......

please suggest me any different method or standard programme.

Thanking you!

regards

What error are you getting when you run this?  I'm guessing it is a resource is already in use (the sample clock).  You need to combine these into a single task.
