Can anyone help?

MS Access �97: -

I have set up a table as example below:

Design     Height   100Wide   200Wide   300Wide
    26           100          10               20               30
    26           200          20               30               40
    26           300          30               40               50

I have created a form where a user enters the design as 26; height as 200;
width as 200

I have created a query, which searches for the design & height entered, but
from this how can I extract the number 30 from the 200wide field based on
the width a user has entered?

All responses gratefully received.
