I'm not 100% sure but I don't think a form can have two recordsource's. You can however place those two source's in a query and have that one query as the source OR you can have you main form and place the second recordsource as a subform.
Aside from building a query with multiple record sources, you could make a sub-form within the main form which has a different record source, and you can link fields from the sub-form to fields in the main form.
