Powershell Function Scoping Issue

Question

Hopefully this is a simple question for the pros out there. Consider a script like this:
function Do-Something {
Helper1
function Helper1 {
# some stuff
I then dot-source this script in a psm1 file which is imported into my local session. The module only exports Do-Something as I would like Helper1 to be private. However, when I run Do-Something then Helper1 is not found. How can I create a helper that is
not exported to the global scope but is still available to the exported function? Should I just put Helper1 inside Do-Something or is there a better way?
Thanks!

OK.  So you have a .PSM1 file that you're loading with Import-Module, and that PSM1 file dot-sources some number of other PS1 files?  That should be working fine; I use that same technique in many modules.  Here's an example of that on my
computer:
#### test.psm1:
function Do-Something {
Helper1
. $PSScriptRoot\Helper.ps1
Export-ModuleMember -Function Do-Something
#### Helper.ps1:
function Helper1
Write-Host 'I am the helper'
#### At the console:
PS C:\source\Temp> Import-Module .\test.psm1
WARNING: The names of some imported commands from the module 'test' include unapproved verbs that might make them less discoverable. To find the commands with unapproved
verbs, run the Import-Module command again with the Verbose parameter. For a list of approved verbs, type Get-Verb.
PS C:\source\Temp> Get-Command -Module Test
CommandType Name ModuleName
Function Do-Something test
PS C:\source\Temp> Do-Something
I am the helper
PS C:\source\Temp>
