Sorry to bother you again
Do you mean create a parameter like this
Customer ID parameter
------------------------ $WADbSearch1->addComparisonFromEdit("quotes.customerID","S_customerID","AND","Includes",0);
Customer Name parameter
-------------------------- $WADbSearch1->addComparisonFromEdit("customers.customerName","S_customerID","AND","Includes",0);
Please let me know if this is right, if not then I just live with search by customer ID only.
