Function wont accept parameter in script

I am having an issue with a function of mine acception a parameter. If I copy/paste the function into the shell and run it then set the variable and call the function it works! But if I run the script the function doesnt accept the parameter. Below is the primary snippets, if you want the whole script let me know.

$user = 'someusername'
#$computer = 'somecomputer'

function PrinterData {
    param(
        [string]$computer,
        [string]$user
    )

    $sqlserver = "CONFIGMGRSERVER"
    $sqldb = "CM_CAS"
    $sqlquery = "
    SELECT  dbo.v_R_System.Name0, dbo.v_R_System.User_Name0, dbo.v_GS_PRINTER_DEVICE.Name0, dbo.v_GS_PRINTER_DEVICE.DeviceID0, 
            dbo.v_GS_PRINTER_DEVICE.DriverName0, dbo.v_GS_PRINTER_DEVICE.PortName0
    FROM    dbo.v_R_System INNER JOIN
            dbo.v_GS_PRINTER_DEVICE ON dbo.v_R_System.ResourceID = dbo.v_GS_PRINTER_DEVICE.ResourceID
    where (PortName0 not like 'LPT%' 
			and PortName0 not like '%HPFAX' 
			and PortName0 not like '%rightfax\spooljob%' 
			and PortName0 not like '%TechSmith%' 
			and PortName0 not like '%pdf%' 
			and PortName0 not like 'Microsoft%:' 
			and PortName0 != 'nul:' 
			and PortName0 != 'SHRFAX:' 
			and PortName0 != 'XPSPort:' 
			and PortName0 != 'CCMS_FAX' 
			and PortName0 not like '%APDCPort%:%' 
			and PortName0 not like '%COM%:%' 
			and PortName0 not like 'c:\%' 
			and PortName0 != 'FAX:' 
			and PortName0 != 'File:'

			and PortName0 != 'FXC:' 
			and PortName0 not like 'iceport%' 
			and PortName0 != 'NVK6:'

            and (dbo.v_R_System.Name0 = '$computer' or dbo.v_R_System.User_Name0 = '$user')"

    $connection_string = "server=$sqlserver;database=$sqldb;Integrated Security=sspi"

    $sqlConnection = new-object System.Data.SqlClient.SqlConnection $connection_string
    $sqlConnection.Open()

    $adapter = new-object data.sqlclient.sqldataadapter($sqlquery, $sqlConnection)

    $set = new-object data.dataset
    $adapter.fill($set) | out-null
    $global:table = new-object data.datatable
    $global:table = $set.tables[0] 
    write-host "--- Found the following printers to migrate ---" -ForegroundColor cyan
    $global:table
}

function PrinterList {
    Param(
        $printerip
    )
    write-host "Printerip: $printerip"

    $mysqlserver = "SERVER"
    $mysqldb = "printer_list"
    $mysqluser = "USER"
    $mysqlpassword = 'PASS'
    $mysqlconnectionstring = "Server=$mysqlserver; Database=$mysqldb; User=$mysqluser; Password=$mysqlpassword"

    $mysqlquery = "
    SELECT       *
    FROM         printers
    WHERE ip = '$printerip'"

    [void][System.Reflection.Assembly]::LoadFrom("D:\scripts\printerinstall\MySql.Data.dll")

    $connection = New-Object MySql.Data.MySqlClient.MySqlConnection
    $connection.ConnectionString = $mysqlconnectionString
    $connection.Open()
    $command = New-Object MySql.Data.MySqlClient.MySqlCommand($mysqlquery, $connection)
    $dataAdapter = New-Object MySql.Data.MySqlClient.MySqlDataAdapter($command)
    $mysqltable = New-Object System.Data.DataTable
    $recordCount = $dataAdapter.Fill($mysqltable)
    $global:mysqltable | select Model,IP,Building,Floor,Printer_ID
}

$dataip = $table.PortName0
write-host "DataIP: $dataip"
$driver = $table.DriverName0
write-host "Driver: $driver"   
$printer = printerlist -printerip $dataip
$printer

I am not sure if its because of the type of data the first function returns or if there is something wrong with my printerlist function.

Any ideas?
