Drop Down List With Linked Fields

I want to create an asp page from these forms in my database:

Database:
Table 1 =>
1.1) ID:
1.2) Product Name
1.3) Description

Table 2 => For the ASP Form
2.1) ID:
2.2) Text field 1 (Normal input field)
2.3) Product (Dropdown Menu, Data Source Table 1, Field 1.2)
2.4) Description (Text Field, Data Source Table 1, Field 1.3)

The Description value should be in correlation with the Dropdown Menu value in Table 1
