Thanks, I exported what I needed to change in csv. Edited that and tried to import it. It gave me this fatal error:

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 128 bytes) in ...../core/lib/data.php on line 484

So I tried to just import the same unedited file I exported, same thing. Am I missing something?

I have 2000 items. They are priced the same, yet the material and size changes the price. The material and size options for every product are the same. Is there a way that I can set a global option with child options that have the price modifiers already set?

Currently, I have made an option and 2000 times I set the modifying options and pricing. Now, with change needed in all the pricing (not just base price), I would have to edit each product. That's 2000 edits, because I can't figure out how to have a global option that I can make pricing changes one time and it take effect across the board of all items in that global option and its children.

Can anyone tell me how I can achieve this, even if I have to edit each one one more time, if I have the global options, any further changes could be made one time for all products.
