SMALL Function Array won't work past 1000 rows?!

[pstreet]

Hi Guys, I'm stumped with this one. I'm using the following formula in column E to return the row numbers of the name I've selected in column A. It works fine for a small array of 1000 rows, but when I increase it to 10,000 for example.... it returns BLANK? - Any Ideas?

=IFERROR(SMALL($Q$2:$Q$1048,ROWS($Q$2:Q2)),"")

Have you entered this as an array formula (Ctrl-Shift-Enter) ?
You're implying you've entered it as a normal formula.

is it exactly 1000 rows? What happens if you increase it to 1001 ?
