Is this possible for Select Expert?

SOLVED

I have this in Select Expert and I need to also include a value that has no VendorNo

{AR_InvoiceHistoryHeader.InvoiceDate} = {?Date Range} and
{AR_InvoiceHistoryDetail.VendorNo} like ["0000833", "001????", "002????", "003????"] and
{@Total Sale} >= 0.01 and
{AR_InvoiceHistoryDetail.ItemCode} like ["/DISC*"]  I need to also include Items that start with /  But these items have no VendorNumber so the second line omits these. I need to to also include /DISC* so I get the discounts comments. I tried OR but that returns orders with only /DISC and orders without ?DISC

Thanks for any help
