Couple Of Modifications Needed - Devs Please Quote

First Modification

Products with options. I need prices to calculate base price + previous options. Please see these most posts for more info

Second Modification

Please look at this product. You will see the options are size, windows and installation. Installation cost corresponds to a certain size. I would like a modification that, once a size is selected, only lets the customer select the correct installation size option. Currently a customer can select size as there is no way to limit the available options.

For example - if a customer selects an 8x8 Shed - the only option that they should be able to select in Installation should be the 8x8 Installation.

Please inbox me with quotes. Keen to get these done ASAP providing price is good.

which product ?

Buy it sounds like you need sequential options instead of simultaneous, then use forbidden combinations, or allowed combinations.

Cheers

This is the product - forgot the link. But actually John, I think you might have answered that. Nice one

Sound, but just remember, the option combinations are probably gonna be dropped in favour of vartiants soon
