May I know which one is appropriate? If both are appropriate, what is the difference?

(1) I noticed none of our colleauges have uploaded thier marking  papers into the share folder.

(2) I noticed none of our colleauges had uploaded thier marking papers into the share folder.

Hi, Josua—You have two misspelled words in both sentences. The difference between (1) and (2) is that, in (1), your colleagues still (at the time of speech, after the time of noticing) have not uploaded their papers, whereas, in (2), they hadn't done so prior to the time of noticing. Choose the sentence with a meaning that goes with the context. That will be the most appropriate one.

Thanks, the typo is noted.
