Further modification to Powershell script

This is a slight modification which is needed to an existing script.

This is a continuation of the assistance I have been receiving today.

Another source file has the following structure for the PO number.
There is a sample of a PO1 and the PID as well below.

BEG*00*NE*99545**20140915~



PO1**20*CA*19.00**UK*12345678945612*PI*1234567~
PID*F****DESC~


 The basic structure for the PO1 and the PID is repeated in the file..

 Sample Script:

 $InputFile = "C:\original.txt"
 $OutputFile = "C:\New.txt"

 Function ParseText ($OutputFile,$InputFile){
Begin{
            $line,$poline,$totline,$total,$i = $null,$null,$null,$null,0
            Set-Content $OutputFile $null
            $Data = Get-Content -Path $InputFile | ?{$_ -match "(NE\*)|(PID\*)|(PO1\*{2})|(EFG\*)"}
      }
Process{
      $Data | % {
      #Check the end of data set
            If ($_ -match "EFG\*"){
                  If($poline -ne $null -and $total -ne $null){
                        $Totline = "Total: `$$Total"
                        Write-host "This is Total `$$total"
                        #Write the data collection to output file
                        "$poline$line`r`n$totline`r`n" | out-file $OutputFile -Encoding UTF8 -Append
                        #reset the variables
                        $line,$poline,$totline,$total,$i = $null,$null,$null,$null,0
                  }
            }
            #Collect the PO Number
            If($_ -match "(NE\*)(\d{0,10})"){
                  $poline = "PONumber: $($Matches[2])"
            }
            #Collect PO1 details and following PID Discription
            If($_ -match "(PO1\*{2})(\d{1,})\*(\w{1,})\*(\d{1,}(\.\d{1,})?)\*{2}(\w{1,})\*(\d{1,})"){
                  $i++
                  $total += [double]$Matches[2] * [double]$Matches[4]
                  $Desc = ($Data[([Array]::IndexOf($Data,$_)+1)] -split "\*\*\*\*|~")[1]
                  [String[]]$line += "`r`nItem $i`: UPC: $($Matches[7]), Desc: $Desc, Qty: $($Matches[2]) Price  `$$($Matches[4])"
            }
      }
 }
}

If(Test-Path $InputFile){
 ParseText $OutputFile $InputFile
}

 How can I modify any of today`s scripts in order to get the desired output?

 Currently the script I am using is not showing anything for PONumber... it's blank after the word PONumber.
everything else is calculated or shown.

 Here is the output desired.

 PONumber: 1234561111
   Item 1: UPC: 12345678912345, Desc: information here, Qty: 248 Price: $10.00
   Item 2: UPC: 23456789123452, Desc: information here, Qty: 329 Price: $1.00
   Item 3: UPC: 98765432198765, Desc: information here, Qty: 20 Price $2.00
   Total: $Calculated total

  PONumber: 1234568888
   Item 1: UPC: 12345678912345, Desc: information here, Qty: 250 Price: $10.00
   Item 2: UPC: 23456789123452, Desc: information here, Qty: 200 Price: $1.00
   Item 3: UPC: 98765432198765, Desc: information here, Qty: 100 Price $2.00
   Total: $Calculated total

What modification to the script needs to be made?
