??? I don't understand this post.

You set your group summon on Sunday to do the event on Monday. That means that you had a try remaining on Sunday.

However on Monday, once you finished the summon capture it says you only have 1/2 tries remaining for the week.

In summary you used your remaining Sunday try from last week and one of the 2 tries from this week to do summon capture on Monday. Just as what was previously reported.
