Populating a table with data from a CSV

I'm trying to import data into a table I have created in SQL2008 Express, I've used the same scripts for other tables and they have worked, I get the following error:

Invoke-Sqlcmd : Invalid object name 'Customer'.
At D:\devinfo\Customer\PullCustEnv.ps1:23 char:14
+ Invoke-Sqlcmd <<<<  -InputFile "D:\devinfo\Customer\TSQL\CSV-Import-CustDetails.sql" -verbose -ServerInstance server1
    + CategoryInfo          : InvalidOperation: (:) [Invoke-Sqlcmd], SqlPowerShellSqlExecutionException
    + FullyQualifiedErrorId : SqlError,Microsoft.SqlServer.Management.PowerShell.GetScriptCommand

Using the following syntax:

Invoke-Sqlcmd -InputFile "D:\devinfo\Customer\TSQL\CSV-Import-CustDetails.sql" -verbose -ServerInstance server1

CSV-Import-CustDetails.sql:

USE DATA
TRUNCATE TABLE Customer
GO
BULK
INSERT Customer
FROM 'd:\test.csv'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO

The table exists and the TSQL script I have run works locally on the SQL server.

Any ideas ?
