Custom Sets

I'm trying to create a custom set and I keep getting an error:

"There was a problem creating your player set.

num cards inserted doesn't match file"

I have 799 hitters; 581 pitchers, and 10 stadiums.

I've tried adding a hitter so there are 800, didn't work. I've tried adding a couple stadiums so there are more than 12, didn't work.

Any ideas?

Same thing happened to me. As it turned out, I had somehow dropped one digit in one player's ID.

Scan your spreadsheet and see if anything obvious jumps out at you.
