Very Simple Problem very urgent plz

I have created two db services to fetch data from different databases(for eg, emp, where place as output & name as input and cmp, where name as input & company_name as output), and i have created a flow service(GetCompany), included above two(emp and cmp) services, and included an input to that service ‘name’, which should get place from emp db service and company_name from cmp db service. But I am receiveing an error like "Could not run the service ‘GetCompany’.

java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot find the input table or query ‘cmp’. Make sure it exists and that its name is spelled correctly.".

can anyone help me out this case, very very urgent
