Help meee!
after months of choosing components i have finally picked everything and i am about to order but i cant because when i try to save changes to the delivery address a error message comes up saying

"Δ Address Line 1 contains invalid characters."

AHHH!

the first line of the address is "Unit C3(3) Centre Court"

Any help will be greatly appreciated!

Im gonna go with C3-3. <<-- this strangely works but brackets dont
I have included the company name so that should be a guide the delivery person on their way, just in case ^^
