Combinations limit

[TC!!]

I've created a site which sells 19 products.

The customer has now asked me to create a pick n mix option where a product allows customers to choose a 4 or 6 pack with a sample from each product they choose.

In the admin for the 4 pack the product has option 1, 2, 3 and 4 which can be any of the available products. When I try to do this and hit 'Generate' it doesn't work. Looking at my own log files I can see the memory is exhausted. I increased the memory limit on my development machine to 512MB but it can't handle the 4 pack option, not even tried 6 yet.

I have been able to reduce the options and get the front end working but the admin breaks so I'm no longer able to edit the product.

Does anyone have any ideas of how to do this kind of thing? I've thought about use thing customization fields but then you'd rely on the customer entering the correct text for each product. I may be able to change my template to replace the customisation text field with a drop down box but I think it's going to be a lot of work.

I am not sure if I understand what exactly you want to achieve, but for me it sounds something similar to the module we made

Have a look.
