I checked the gallery’s program, but just as I had thought, it did not have any notable events. (Singular gallery is just gallery and you add an s for the possessive, noticeable is not the appropriate word choice)

thank you Dina and Mohammad

I checked the gallery's schedule, but , as I thought, they had no current event.

After checking galleries program , It appeared they didn’t not have any noticeable event as I expected.
