Im new to Sharepoint.

 In need to know , how to fetch the x1 , x2 values from one form to another form x1, x2 fields, this wants to happen when 2 forms ID fields(Drop down field) are same.

ex:

first module I have 3 fields like, "Marketing ID" , "Company name" , "Vendor name".

second module I have the same related fields like "Marketing ID" , "Company name" , "Vendor name" and some more fields.

now i need to fetch the information from 1st module to 2nd module ( "Company name" , "Vendor name" ) when I select the Marketing Id(Drop down - field)

Can someone make a suggestion on how I can do this.

Thank you so much for any help you may be able to provide.
