Dynamic Drop Downs question

[farris12]

I'm using Dynamic Drop Downs for my situation:

Selling Paint:
1. Dropdown:
- 2,5 Liter
- 5 liter

2. Dropdown:
If chosen 2,5 Liter:
- White, + 0.00
- Light colours, + 5,00
If chosen 5 Liter:
- white, + 0.00
- light colours, + 6,50

But I can't link the second dropdown to the first...
White isn't a problem because it's always + 0.00, but Light Colours is + 5,00 at 2,5 Liter and + 6,50 at 5,0 Liter... How to do this??

Thanks in advance

are dependant attributes totally impossible? There has to be some funtcion for it? I think you only need AJAX for it... If needed I can maybe help with ddevelopment?
