This thing is driving me crazy ... trying to get the a loss carried forward and partially claimed data from previous years that I'm filling on the Supplementary Schedule 4 form  to show-up the correct numbers on the main Schedule 4.

The numbers are all wacky ... when doing overrides the form doesn't appear to follow the CRA intent yet overrides are necessary to get the Supplementary form's data to match-up on the main Schedule 4.

Grrrrr....
