Past perfect continuous with verb "fall" as the second condition
Is "fall" in the sentence below in its correct conjugation?
"Had this been related to an existing cases, or fall within the supported thresholds, we would have..."
"fallen" does not sound right to me in there.
Thank you, tsdn
Solution 1:
The sentence is flawed. Two corrections are needed: "cases" is plural and should not follow "an"; "fall" should be in the same tense as "related". I suggest it should read "Had this been related to an existing case, or had it fallen within the supported thresholds, we would have..."
