i am having problems saving and using a stair i created, it comes up with an error sign every time i try to save it yet says the stair is fine when i check the stair? how do i fix this? thanks

Hard to say with such a general error message.

I'd first try changing the '0' upper floor thickness to 0.0001. If that doesn't work then one by one change the other parameter values until you figure out which one is generating the error.

just tried your suggestion, but it didnt work, also tried making another stair where i just put in a different height, and it still came up with the same error....
