T4E error message, you have reported amounts in boxes 15, 17, 18, 33 or 36 you need to report in box 14. Box 14 already entered

The simplest way to fix this error is to delete the T4E and re-enter the slip.

I tried this, it didn't work. 

Be sure that you enter the proper amounts in the proper boxes. If you did, and are still having issues please contact our customer service for assistance.
