getting value to a variable from a point label

[Kaanven (Kaan)]

I am trying to get a value for a variable in the graph from a label of a point. So to explain more detailed:

1. I add a point A = (1,1)

2. Then a define a variable a = 0 for start

3. then I add a editable label to the point A

4. Finally i want to get a value for variable a by typing in the label from the graph.

I have also tried something like this but it gives an error saying static evaluation of BinaryExpression has not yet been implemented.

Please if someone has any idea share with me.
