How To Link Form And Subform

Hi every body. i made a bounded data entry form that is based on a form and a sub form. But when i try to run it i get many errors. I be happy if some one help me how i link these two tables since draging the sub form to the form did not establish the reletion automatically! I be happy if some one teach me how to link form and sub form together. Below u can see the two query which is for the main form and sub form.thanks
