I think that I could get a checkbox to go out and do something after someone
checked it - But can I set the value of a checkbox based on the value in
some cell?

Example - I have a checkbox cleverly known as Checkbox 15;
I would like that checkbox to set itself to being checked when my user
places a value in the cell F26

doable? and how?

Users could set this checkbox themselves but always forget....thanks ahead
of time
