I have a little problem i hope someone could help me
with...

How can i get Excel to check if a specific cell is
entered, and when this specific cell is entered run a
function???

e.g.
I wish to run function: show_graph when the user scrolls,
clicks or enters cell("B19").

I seem to have some understanding of it, but my function
needs that the user press enter in the desired cell. I
wish to activate the function even if the user scrolls
through it.

I hope that someone knows how.

Thx in advance
