I created an integer field with a calculation to display the highest number from 4 other integer fields. So for field ${highest_number}, the calculation is max(${field1}, ${field2}, ${field3}, ${field4}). Using these numbers as an example: 450, 290, 875, and 1285; 875 is returned as the max number because I assume it starts with the highest number but obviously 1285 is the highest number. Any ideas on what is going on?
