Does anyone know how I can step between different voltages say from a list or table for a Agilent E3631A?

Question

I am just getting started with Labview. I have the 8.0 version installed.
I currently trying to get the E3631A power supply to step through a list or table of different levels. For example: 2.0,1.8,1.53,1.25 and so forth. Is there anyway that I can create a panel where the user can enter the desired values in a list or table then, he/she can scroll through that values one by one by clicking a next button.
Thanking everyone in advance for your help.

If you want to update both outputs at the same time, you use a single shift register for the array index and wire it to the index array function to get the value. I've modified your last example to show how this would be done. I also cleaned up the wiring some. I also put the initialize and close outside the while loop so each is only done once. It also looks like the initialize function you are using needs to be modified. I suspect that it is a version that uses 'Old VISA Open'. This can cause problems. Open this VI and if the 'Old' is there, right click on it and select Replace and browse to the regular VISA Open on your palette. This will disconnect the string that used to be the gpib address. Delete the string control for address. Right click on the VISA reference and select Show Control. Go to the front panel and wire the VISA reference to the connector pane where the string control was. This should be the upper left most connector. Now you can use a VISA Resource Name on your VI's front panel.
