I am pretty new to macros. I'll try to explain my issue the best I can.

I need rows 10-20 on worksheet A to hide when the value of D3 on worksheet B is equal to 0, and to automatically unhide those rows when the value is anything greater than 0.
The value of D3 is calculated from various cells on worksheet B, so a user would not physically change D3's value.

Please let me know if I need to explain anything further. Thank you in advance!!
