Column totals automatically return specific words dependant on what the total is
I have a two page pdf form where the user puts a tick in the appropriate box. At the bottom of the form, the ticks in each column are added up. This sub-total (sub-total_1) is then multiplied by a specific number (column 1 is by 1, column 2 is by 2, column 3 is by 3 and column 4 is by 4) to give sub-total_2. Both sub-totals 1 and 2 are then added to give a final total for each column. All four column totals are then added to give a final figure. All of this works.
Based on the final total, I would like the form to automatically write:
Low if the total is between 0 and 20;
Moderate if the total is between 21 and 33;
High if the total is between 34 and 46;
Extreme if the total is 47 or more.
Is this possible and, if so, how do I do that?
I'm using Adobe Acrobat Pro DC, 2015
