Add mercies to custom Paladin class

[Daijin]

Can someone please explain to me what I need to do to enable Paladin mercies on a custom class? I have figured out how to make all changes needed (and reason its a custom class and not a archtype is because i could not figure out how to add psionic spells to the archtype.) But I cannot figure out how to enable mercies. I searched and read for over 5 hours on google and hero lab and there are some mentions but it was not clear enough for me. (I do not use Youtube, i am deaf and their captioning is frustrating.).

Please help.

Is your class using any of the custom special ability tables already? If so, then the fields I mention will have to be changed slightly so they apply to one of your free tables.

In the editor, go to your class helper. Add the following eval script to overwrite the default candidate expression field.

Final 99999999 (this is eight nines!)

field[cCstSpExpr].text = "abCategory.PalMercy"

Now you need to make it so levels in your class count towards meeting the pre-requisites of any Paladin Mercies. Hit the "tags" button in the upper right. Add another tag, and for the tag ID enter "PreReqCaP1", then for the value enter "PalMercy"
