I have fixed your vi, please download it and make sure the libraries attached correctly
The corrections that I made was:
When taking data from the front panel make sure that the data type matches to the function data types
Corrected one data type in the function 'setsimpletrigger'
Please note that I set wavetype as 3 this means the DC voltage, if you selected it using your drop down it would be 0 which is a sine wave.
Also pktopk and offset are both in uV NOT mV.
To get a 1V dc signal set the offset to 1000000,
the startfreq to 1000
and stopfreq to 1000
and leave the others.
