    Hi @AATester ,

    If both scripts are in the same folder maybe this helps.

    First script: 

    # Script-file JustAtest.ps1 with function  
function ABCDE{  
    [CmdletBinding()]  
    param (  
        $ComputerName  
    )  
    Write-Output $ComputerName  
}

    Second script calling the fist script: 

    # Script Call-Script.ps1 calling another script "JustAtest.ps1" in the same folder  
# relative path  
.\JustAtest.ps1  
ABCDE -ComputerName Computer12  
  
# fullpath  
C:\Junk\JustAtest.ps1  
ABCDE -ComputerName Computer13  
  
# fullpath  
& "C:\Junk\JustAtest.ps1"  
ABCDE -ComputerName Computer14  
  
# fullpath  
. "C:\Junk\JustAtest.ps1"  
ABCDE -ComputerName Computer15

    Are you sure the path is correct?

    . C:\Users\myname\Documents\Files\P.ps1

    I ran a PowerShell script (Untitled-22.ps1) with the current directory set to "C:\Junk" and in it I dot-sourced the file C:\Excel\myname\Documents\Files\P.ps1. Here's the script using the function ABCDE from @Andreas Baumgarten ): 

    . C:\Excel\MyName\Documents\Files\P.ps1  
ABCDE -ComputerName Computer12

    This was the result:

    PS C:\junk> .\untitled-22.ps1

    Computer12

    Adding . .\Path\P.ps1 in b.ps1 worked for me when both files are in the same path. I ran b.ps1 directly from the path to pick up a function in P.ps1, it worked fine. Now the problem is that when I try to execute b.ps1 from javascript, it throws error that the b.ps1 is not recognized as the name of a cmdlet, function, script file, or operable
    program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

    Hi there,

    It would be great if you share your script which would result in easier troubleshooting of your issue.

    Generally, if you are calling the function from a remote PC then you must Enable-PSRemoting on the remote machine where the script is executed.

    Enable-PSRemoting -Force

    Also, make sure you are executing the script with the right privileges and the account which you use for running scripts has all the permission to access the file that you are trying to call.

    In PowerShell, the Get-Acl command can be used to retrieve NTFS permissions reports. The script mentioned below helps retrieve the ACL set on the C:\commands folder.

    (Get-Acl -Path C:\commands).Access
