well, think it should have worked. "00/01/1900" is simply a zero returned by
the vlookup for blank cells where the formula cell is formatted as dd/m/yyyy.

Here's a quick sample to illustrate that it works:

Hi Max

I tried this, but it didn't work. I also tried replacing the 0- with "" or "

Seemed such a neat idea too.
