invoke command - scriptblock error

What used to work in my script doesn't anymore and I am out of ideas.

I'm trying to do the following:

Import-Module 'H:\folder\folder1\Remove-Software.psm1'
$sessionoption = New-PSSessionOption -SkipCACheck -SkipCNCheck
$s = New-PSSession -ComputerName $Global:DevicePrimaryIP -Credential $Global:Creds -SessionOption $sessionoption
Invoke-Command -Session $s -ScriptBlock $function:RemoveSoftware

This should log into the remote software and remove software, however I keep receiving the following error:

Invoke-Command : Cannot validate argument on parameter 'ScriptBlock'. The
argument is null. Provide a valid value for the argument, and then try running
the command again.
At line:1 char:41

Also, I've tried every combination for the scriptblock I can think of.

I've changed things elsewhere in my script but haven't touched this for some time. If anyone else can see the problem anyhelp would be appreciated.

You don't seem to have a function RemoveSoftware in your script. - Ansgar Wiechers
The function is imported from another module - Mike
Within that module it contains a function called removesoftware (No hyphen) several processes and directories that are killed/deleted. No arguments are parsed to it either, just to run a small snippet of code on the remote server: function removesoftware{ kill process delete directory return "software has been removed" } - Mike
What happends if you run $function:removesoftware alone? Just to see that the function is defined - Frode F.
I believe this is where my problem is.. It doesnt actually do anything, also autocomplete doesnt see it. I must be missing something, it has been imported, I can browse to the directory where this module is located too. - Mike

Your function is not imported from the module. You can use -Verbose to see what's imported. Ex:

Import-Module .\Desktop\testmodule.psm1 -Verbose
VERBOSE: Loading module from path 'C:\Users\frode\Desktop\testmodule.psm1'.
VERBOSE: Exporting function 'testModuleFunction'.
VERBOSE: Importing function 'testModuleFunction'.

If the "module" is just a script-file with a few functions you could try to simply dot-source them in:

. 'H:\folder\folder1\Remove-Software.psm1'
