Excel query question

I have written an excel function like below:
="WHEN mynumber >= '" & D65 & "' AND mynumber <= '" & E65 & "' THEN '" & A65 & " " & B65 & " " & C65 & "'"

The above mostly works the way I want. But if there value of C33 is null, it ends in an empty blank character at the end of the calculated value.
Could you suggest how I could get rid of the empty character. I trid TRIM function but could not make that work.

Thanks a lot.

* You could use my Better Concatenate function.

* You will probably need to use an IF() function to check the existence of a cell and only prepend the space character if there is something to concatenate.

* If C33 is the only cell that might be empty, you could Trim the result.
="WHEN mynumber BETWEEN '" & D33 & "' AND '" & E33 & "' THEN '" & Trim(A33 & " " & B33 & " " & C33 & "'")

Thank you. I will look into the Better Concatenate function. But for now I tried:
="WHEN mynumber BETWEEN '" & D33 & "' AND '" & E33 & "' THEN '" & Trim(A33 & " " & B33 & " " & C33 & "'")
But this did not eliminate the last character coming out of null E33 value.

Trim each of those cells as well.
="WHEN mynumber BETWEEN '" & Trim(D33) & "' AND '" & Trim(E33) & "' THEN '" & Trim(A33 & " " & B33 & " " & C33 & "'")

Thank you. But sorry this does not remove the last blank space "before" the ' character (single quote character) at the end.
Because the Trim(A33 & " " & B33 & " " & C33 & "'") is not trimming before the ' character.
I tried to modify the above to bring the 1st bracket before the ' character but I get syntax error.

Sorry.  Misplaced parenthesis for that original Trim function.
="WHEN mynumber BETWEEN '" & Trim(D33) & "' AND '" & Trim(E33) & "' THEN '" & Trim(A33 & " " & B33 & " " & C33) & "'"
