How do I get Powershell to write specific text it finds in a text file?

Here is sample data I need to look through:

ABC*00*          *00*          *00*123456789     *01*123456     *123456*1234*^*00123*000000123*0*P*>~
GS*PO*9988776655*0123456789*20140909*0123*123*Y*123456~
ST*555*00123456~
CDE*00*OP*12345**20140908~
PO1**12*CA*1.00**AD*123456456456*OP*123123~
PO4*10~
PO1**15*CA*10.05**DD*12313123213444*AB*012132~
DZA*D****TEST3~
PO1**10*CA*11.22**AA*99991132123231*AB*989889~
KLM*B****TEST2~
PO1**20*CA*12.00**KL*1231321332123*AB*756465~
EFG*A****TEST~
FGH*0*000000123~


I want the output to be:

PO Number: 9988776655
Total Value: $274.95

Here is a script:
It will not display the PO number correctly at all:

$InputFile = "C:\Data\original.txt"
$OutputFile = "NewData.txt"

[double]$Total = 0
($Input = Get-Content -Path $InputFile) | ? {$_ -match "PO1"} | % {$col=$_.split("*");$total += [double]$col[2] * [double]$col[4]}

$Totline = "Total: $Total"
write-host "This is Total $total"

[double]$PONumber = 0
($Input = Get-Content -Path $InputFile) | ? {$_ -match "PO"} | % {
      $Columns = $_.Split("*")
      $Sub += [double]($Columns[3])
      write-host "This is the PO Number $PONumber"
}
$poline = "PONumber: $PONumber"
@"
$poline
$totline
"@ | out-file $OutputFile -Encoding UTF8

How can I get it to display the PO Number, which in this case is 9988776655 ?

Try..
$InputFile = "C:\Data\original.txt"
$OutputFile = "NewData.txt"

[double]$Total = 0
($Input = Get-Content -Path $InputFile) | ? {$_ -match "PO1"} | % {$col=$_.split("*");$total += [double]$col[2] * [double]$col[4]}

$Totline = "Total: $Total"
write-host "This is Total $total"

[double]$PONumber = 0
GC $InputFile |?{$_ -match "(PO\*)(\d{0,10})"} | Out-Null

$poline = "PONumber: $($Matches[2])"

@"
$poline
$totline
"@ | out-file $OutputFile -Encoding UTF8

Thanks.  This works, however it does not display a $ before the actual dollar value of the total.  
How can I add that?
