Add a new function in the myadopts page?

[Infernette]

I wanted to edit in another function to the myadopts page (to go with the rename options and whatnot) but I noticed that simply just copying the rename function and changing the name causes an error, so what other pages/parts do I need to edit?

Also, I was wondering, how do we go about updating a part of an adopt (I see that it has "setName" and such in the rename function, but can that jut be changed to a field I want updated or do I have to find some workaround? Sometimes It can just be changed or sometimes it refuses.........)

I'm using this to try to update my public selling/buying mod that I had on my old site. :)
