activate reverb

new user here. when i go to effects, i cant open the reverb feature.

Which version of Windows?
Which version of Audacity? (look in “Help > About Audacity”)

Why not? Is it listed in the menu? Is it greyed out? Is listed but fail to open? Does it throw an error?

i solved the issue. thanks.

What was the problem? It is helpful for other Audacity users when solutions are published.
