Issue with array length property

Hello. I am new to PS but a novice programmer, mainly in Java. I am modding a script I found on this site to collect the relevant data that I need and am confused by an array length. The code returns an array that has one object in it but when evaluating the length, it the array evaluates to less than 0. What am I missing? 

The output of this section of code is as follows:

Done with VerifyConnectivity function. Now testing Responded.count which = @{Computer=Frobozz01}

Responded < 0

compList = 'Frobozz01 DummyComputer01 DummyComputer02' \nAssigning global:Dead to compList

tempCompList is now == to: 'DummyComputer01'

computer = '(@{Computer=DummyComputer01; IPAddress=; Responding=False} | select computer)'

tempCompList is now == to: 'DummyComputer01 DummyComputer02'

computer = '(@{Computer=DummyComputer02; IPAddress=; Responding=False} | select computer)'

Final tempCompList is: 'DummyComputer01 DummyComputer02'

Now assigning tempCompList to compList

End of while loop

The code is as follows:

functionGetInstalledSoftware
{param ( [parameter(ValueFromPipeline=$true)] $compList ) BEGIN
