Hi there,

I would like to achive to things using Javascript.

1. I have 2 dropdown lists where a user can choose models for a photo shooting. In a third dropdown list the user can select how many photo sets should be produced. If the user seletcs only one model there should be 1-4 shootings available, if he selects two models there should be only 1-3 shootings available.

2. We also have couples which appear as "one" model. If a user selects a couple he should not be able to select another model from the second dropdown list. The other way around would be also a possibility. I start with one dropdown and if the user selects a "single" model the second dropdown should appear.

Is that possible? If yes, could you give me an idea how to do this?

Thanks fro your support,
