VLOOKUP returns N/A - Need to return blank cell

Hi,

I have a normal VLOOKUP of this loookup range:

A 1
B 2
C 3
D 4

=VLOOKUP(T14,U6:V9,2,TRUE)

If the value in T14 is in the lookup range, I get the expected value returned. If the value exceeds the vlaues in the lookup range (e.g. I enter "E"), I get the last value in the range (4).

How do I get it to return a blank cell if the entry in T14 is not found?
