I have one field for the number of volunteers the event can have (let's say 1-5). Another field for different groups that are going to attend (this is a multiple select field with the group names). Is there a way to have a "FULL" field that flips to full if the number in field 1 matches the number of groups selected in field 2? So for example we can have 3 volunteers, once 3 groups are selected the 3rd field would flip to FULL.
Next level would be if it was less than 3 to have the field say SPACE AVAILABLE, and if over 3 were selected it would say OVER CAPACITY
