Automating Goalseek When moving points on a graph
 

I have created a macro that activates points on a graph so
I can move them to change the slope of the graph. After I
move the points, the goalseek input box appears, and it
requires me to enter the cell reference so it can change
the value of that cell, then it finds a solution and asks
if I want to keep the solution. I want the macro to
automatically enter the cell reference and click 'ok' to
keep the solution after I move the graph point. Is there
a 'wait for user entry' command or something else I can
use to do this?
