Ok, so I have a table, picture a calendar format to make it easier. Basically a bunch of squares.
Then each "day" needs to have text in it from either group A or group B. So, taking the calendar example, Mondays would be group A, Tuesdays Group B, Wednesday Group C, Thursdays A, Fridays C etc. Basically whatever group on whatever day.
This text is selected from the group lists. So group A might be a group of animals, group B might be a group of cars. Whatever.
So this could be done with dropdowns. But I want them to auto fill. Maybe press a button to run a script? Then all the "days" would populate, with none of the for eg Mondays being the same animal. or that same animal appearing on the other days Group A animals are selected.
Taking this further, if we added another tab/"month" then it would do the same without again repeating the animals already used. OR only repeating them once the end of the list of animals had been reached - so it would cycle through the list.
Any ideas?
