Simple Date Comparison Formula - When Two Dates Are Equal To Each Other

Report I generate once a month that checks to see if tasks are done on or before their due date. Sometimes it works, and others it doesn't...

The basic formula is: [Code] .....

If they closed their task by or before the due date, the condition should be true and it should output "Compliant" beside their task. Otherwise their "Over Due".

The forumla works except when they close their task ON the due date. No matter how I tweak the forumla, it thinks the condition is false as if it cannot tell when the two dates match.
