Autoindexing

[Tom Ray [Lists]]

Hey, I have a really simple question (I hope)..I have a database that 
has a field in it that autoindexes the number. I screwed up and imported 
a bunch of wrong data. Up to row 200 it's right, beyond that it was 
wrong so I had delete it all. The problem now is the autoindexing is set 
to 1105, I want to change it so the next insert gets a number of 201 not 
1105.

I've tried to change it via phpMyAdmin but it keeps going back to 1105. 
Is there anyway I can do this?
