Math in Otter

[Jonathan.Engstrom]

OK, so I have a simple few lines of code I want to run a server checkout on to validate memory is correct. $MEM is a server variable, and the rest is just math. Anyone else any luck doing multiplication in Otter?

I know from doing a write-output of my variables that it is not doing the low or high variables:

    $MEM = 16
    $Win32_ComputerSystem = Get-WmiObject -Class Win32_ComputerSystem
    $ServerMEM = ($Win32_ComputerSystem.TotalPhysicalMemory / 1GB)
    $Low = $MEM * 0.95
    $High = $MEM * 1.05
    (($ServerMEM -ge $low) -and ($ServerMEM -le $High))

Product: Otter
Version: 2.0.10

You can use $PSEval for this pretty easily:

set $a = 2;
set $b = 3;
set $c = $PSEval($a + $b);

Hello, after trying for a half hour, I was not able to get the $PSEval to successfully do any math operations for me, but something I hadn't tried in my hours of troubleshooting this is try putting the variable last and the number first, and the PSEnsure worked great at that point.
