Remove Errors in list

Question

I made a formula that returns a list, each list item is text type.
My problem is, i want to know if there are items that is a number, then I do this:
List.Transform([My List], try Number.From otherwise null)
The 'try <> otherwise <>' is not working, it not returns null, it returns a error, but that's ok, if returns an error is because is not a number. Then my problem starts... I tried everything to remove errors inside the list or chance them to
"null" but nothing works.
Any idea??

You need to write that in the form of a function:
List.Transform(list, (value) => try Number.From(value) otherwise null)
or using the "each" shorthand,
List.Transform(list, each try Number.From(_) otherwise null)
