PowerShell - I can't get "get-help" to work within a script

At the PowerShell command prompt, "get-help get-WindowsFeature", it works.  I can see the output.

But when I place that same command in a PowerShell script, I get an error.

Does the get-help command need an absolute path when run from within a script?

I'm using Windows Server 2012 R2.

Please see attached.

In the text file, you have a bunch of spaces at the end of "Get-WindowsFeature". Try
$commands = Get-Content PSCommands2.txt 
Foreach ($i in $commands) {
	Get-Help $i.Trim()
	Write-output "This is $($i.Trim())"

For future reference:
1.  get-command | select object-name > PSCommands.txt
2.  write-output " " > manual.txt   # empty the "manual" file for this iteration
3.  $commands = Get-Content PSCommands.txt  # Load the $commands variable with the contents of PSCommands.txt, i.e. the list of all the PowerShell commandlets that are available with this particular installation / configuration of Windows Server 2012
4.  # Here is the loop:
foreach ($i in $commands) {
write-output "Working on $i"  # Progress indicator - this will take a few minutes to complete
write-output ">>>>>> $i <<<<<" >> manual.txt  # So I can quickly navigate to the command afterwards, I'll label the beginning of each command
get-help $i.Trim() -Full >> manual.txt   # This is the heart of it - use get-help (with "Trim" to remove the white space)
                                                                    # for each commandlet, and append it to manual.txt
