Multiple Criteria In Select Query With 1 Like

Hi,

I'm trying to build a select query where it prompts the user for a few parameters. I've been having issues where people would misspell the vendor name and nothing pops up. I changed the vendor to Like [Vendor Name] & "*" but now I can't use the parameter of PO# without everything popping up. I have attached the SQL view. Thank you for any suggestions.

SELECT [Main Payment].[Batch#], [Main Payment].VendorName, [Main Payment].VoucherPrefix, [FY08 PAYMENT detail].VoucherNumber, [Main Payment].VoucherSuffix, [FY08 PAYMENT detail].Vchline1, [FY08 PAYMENT detail].PONo, [FY08 PAYMENT detail].InvoiceDate, [FY08 PAYMENT detail].InvoiceID, [FY08 PAYMENT detail].Amount
FROM [Main Payment] INNER JOIN [FY08 PAYMENT detail] ON [Main Payment].VoucherNumber = [FY08 PAYMENT detail].VoucherNumber
WHERE ((([FY08 PAYMENT detail].PONo)=[Enter PO#])) OR ((([Main Payment].[Batch#])=[Enter Batch #])) OR ((([FY08 PAYMENT detail].VoucherNumber)=[Enter Voucher #])) OR ((([Main Payment].VendorName) Like [Enter Vendor Name] & "*"));
