administrative techs/incorrect numbers

[psujaye]

Question about administrative techs-
Boys JV game- about 2 mins into the 1st quarter, the table calls me over and states that 2 players currently in the game have incorrect #s in the book. We assess two administrative techs and move on.
Now the first sub comes into the game with an incorrect number (same team). We assess a third administrative tech (coach now tells me they got new uniforms and he didn't update their numbers..he wasn't upset with us, just angry with himself).
Now we're in the 3rd quarter; about 3 mins in, the table calls us over again. Apparently a player that played in the first half with an incorrect number was in the game in the 3rd quarter and we did not assess a technical in the first half for him. I told the (other) coach that we could not assess a technical now since it wasn't a correctable error (i.e. we needed to catch it in the first half when he first was in the game).
I haven't looked this up in the rules/case book yet- any thoughts on how we handled it?
