I have a question about something that came up in a game I was playing(against a friend). I was making a support attack roll and got a critical hit. I added 1 to the number of clix healed. Is that right? It made sense to me since support rolls are not intended to do damage. On the same note should crit misses on support rolls do 1 click of damage to the fig being healed? I think so because of botched first aid.

Any thoughts or the facts would be appreciated

Page 12 of the Indy Rulebook covers this scenario. You do indeed add 1 click of healing to the roll if you roll a critical hit. A critical miss will result in the character being healed taking 1 click of damage.
