A question about functions...

Hi There,
 
I have been trying to put together a simple function that takes in 2 argumnets. I then want to split them into arrays and try to return a given element of each. here is my code:
 

$StrOne = "1,2,3,4"

$StrTwo = "A,B,C,D"
 

function DoStuff
{param ([string]$Numbers,[string]$Letters)
 

  $ArrNum = $Numbers.split(",")
  $ArrLet = $Letters.split(",")

  #write-host $ArrLet[0]

  write-host $ArrNum[3]
 


}
 

DoStuff($StrOne,$StrTwo)
 

But...i dont understand how it is returning both elements when (4 & A) when the letters array split is commented out.
 
Where have i gone wrong?
 

Its due to the way you are passing the values...it is slightly different that you would with VBScript

$StrOne = "1,2,3,4"

$StrTwo = "A,B,C,D"
 

function DoStuff
{param ([string]$Numbers,[string]$Letters)
 
  $ArrNum = $Numbers.split(",")
  $ArrLet = $Letters.split(",")

  #write-host $ArrLet[0]

  write-host $ArrNum[3]
 


}
 

DoStuff $StrOne $StrTwo

cool, thanks for letting me know:)
