AutoInput UI query variable setup errors

Hi at all.

I have a sort of calendar of 2 weeks, from Monday to Sunday, and, for every day, different time, from 12-13 to 23-00 (12-13, 13-14, 14-15, and so on).

Every time can have a different state, occuped or free.

Now, i would like to do a task that open this calendar and control, day to day and hour to hour, the single state and, if the state is free, tap on it.

I tryed autoinput ui query but... when i use variable setup, screen capture, i have different array...

For example:

Array: Monday
Array: 11-12
Array: occuped
Array: 12-13
Array: free

And so on.

I select one array, for example 12-13 but, when i tap Ok, i have the dialog window with:

Name for 11-12
Chose variable name for field with text "11-12"

Variable name have to be all lowercase.

Why i select array 12-13, and appear name for 11-12?!

Ok, next question.

One time i have different variable name for the different array, for example:

Array: 11-12
Name: first

Array: occuped
Name: firstoccuped

Array: 12-13
Name: second

Array: free
Name: secondfree

How can i controll this variable state and make a task that tap on the variable if it is free?

Thank for your solution, i'm new in Tasker (i have tried Macrodroid too, but i have same problem) and i try to make this task but... it's too complicated for me
