WMI returning- '' is not a valid floating point value

[mrfrosty]

Hi,

I have a number of WMI tests which work fine, however trying to use WMI tests for the following tests always return '' is not a valid floating point value, no matter which machine I try it on.

select PercentFreeSpace from Win32_PerfFormattedData_PerfDisk_LogicalDisk Where Name = "C:"

select ProcessorQueueLength from Win32_PerfFormattedData_PerfOS_System

All machines that I try it on, I'm a member of the administrator group, machines tested are XP Pro SP2 and Windows 2003 Server SP2.

Anyone know how to resolve this?

I assume you forgot to specify value to compare (Test Properties dialog).
