Editing TID and SID in PKHex for Gen 5 Help.

[NathanBelmont]

Hello, I thought I had this figured out but apparently not.

Trying to edit Some Pokémon I moved up from gen 3 through 4 and into 5.
want to change their TIDs and SIDs

=TID16=56278
.TID16=45241
=SID=47213
.SID=64578

I thought this command would do what I wanted, but it is not modifying any of the Pokemon I want changed.
Any assistance would be very much appreciated, please and thank you

Use the drop downs; `SID` is not a valid property.
