Since a primary address can be 0-30, you only have a small chance of having a default value in a driver match what your instrument is set to. I usually leave the resource name blank. Also, you shouldn't have to type anything. Right clicking on the arrow of a VISA Resource Name control will display a list of all instruments detected by MAX.
As far as the problem, are you using the IVI or native LabVIEW driver? If you don't know, then open the VI and see if there's a bunch of subVIs that you can view all of the source code or if there's a Call Library Function Node. If you're using the IVI driver, it will be harder to find the problem and unless you have a copy of LabWindow/CVI, you won't be able to fix any problems. If you're using the native LabVIEW driver, try to determine which subVI is generating the error. All getting started VIs consist of several subVIs (that you can call separately). Try single stepping through the subVIs until the error occurs.

The Error -420 means the instrument was addressed to talk, but but the command sent to it was not a query command. If you are using the getting started vi, see if there is a "ID Query" input, the default value for this input is true, change it to false and see if that helps.
Also have you have checked the instrument's user manual for the valid commands to use? Some instrument requires certain termination character with a command.
