Strategic Modeling - Associating custom dimension not working!

Content

I have a simple revenues model based on standard template, where the sales account (v1000) forecast method is volume x price. I need this calculation to take place for five revenue types (Custom Dimension: RTYPE1, RTYPE2 ...). After assigning the custom dimension to two memo accounts (volume & price) and to the sales account, I am able to create the formulas i.e. Sales | RTYPE1 = Volume| RTYPE1 * Price | RTYPE1 ....I enter the volume and price per revenue type correctly, but when I see the results in sales it keeps repeating the same amount for all revenue types.

Can you please help?
