Ok we sort of figured our the attributed on simple products.
The system we would move from is custom and you click from the product tick next to all dates in the year a course starts and press done. So this system feels very easy for the staff, I am not sure this way will look so easy but we do gain more magento features.
Most courses are set up once and new dates are added for the year once a year, so not impossible.
Once course is added add all monday’s for the year as start dates. (50 dates a year per course)
Then each course has prices for 1 week, 2weeks, usually up to 48weeks (but other types have 1 to 10 week pricing)
So at the moment these are separate screens. You can choose any number of weeks combined with one of the start dates.
I think in magento we may have to set each duration for each start date (alot of options!!) wouldn’t we?
