Hi there,

I'm having some hard time trying to define "up values" to subscripted
variables, what I would like to do is (Latex notations)

d_1 /: Equal[d_1,0]:=False

Ok, I know that the full form of d_1 is Subscript[d,1] so I've tried;

Subscript /: Equal[Subscript[d,1],0]:=Flase


d /: Equal[Subscript[d,1],0]:=Flase

but none seems to work, I get the error message:

TagSetDelayed::"tagnf": "Tag d not found in False==0.

which I don't understand.

Any idea?
