Hi all, I need your help on this please: I have 1 table with day, hours and minutes of the day, this is being assigned to 1 person, when doing this for several days on the week, I need to know, the next available hour of the day to be assigned. Example for guy "Doe", I assign monday from 8am to 10am, tuesday from 9am to 11am. For guy "Johnson" I assign monday from 10am to 11am and I want to assign the same hour for tuesday, but I need the system alerts that hour is already in use, next available hour will be tuesday 11am.
Doe Monday 8am - 10 am Johnson Monday 10am - 11am
Doe Tuesday 9am - 11 am Johnson Tuesday 10am - 11am (error) must be (11am -12m)

T.I.A.
