Hi,

I have this code in a cell:

Subscript[H, 1] = 110; Subscript[H, 2] = 90;
H = Subscript[H, 1] + Subscript[H, 2];
Tanh[Subscript[H, 1]]

The first time I execute the cell, I get

Tanh[Subscript[200, 1]]

which of course is nonsense.

A second execution, yields the correct answer:

Tanh[110]

Is this a feature that I don't understand or a bug?
