Enumeration items must be Unique error (Using SCPI)

Hello,

I'm controlling the Agilent N9010a Spectrum Analyzer with Labview. In my program I need to select the VSA89601 mode but I couldn't find a block in the Agilent drivers for that purpose so I'm trying to do it with a SCPI block. With this SCPI block I can choose every mode available in the spectrum analyzer after creating a Constant. When I try to execute the program I get this error: " Enum constant 'Application Mode Selection': Enumeration items must be unique."

I'll appreciate some help with this error. If anyone knows where to find a Mode Select block in the Agilent drivers tell me please.

Thanks!
