One very important difference is that your original version creates three variables on-the-fly. It then copies the input into these variables, just to perform a simple addition. This could have a fairly severe performance penalty in a inner loop. David's version doesn't suffer from this. The performance hit is a onetime compile cost, from there it will run just as fast as prefix notation.
As to the actual macro syntax errors you had, I haven't a clue...
