Unruly chart
 

I am charting monthly call volumes in a line graph in which I have 7 series
(a different line of business). Each series takes 12 cells of data,
corresponding to each month of the year, which I have in a different
worksheet. Usually I can hit Control and individually click the different
cells so that they are all included in the Values, but for some reason this
time, I get to the 10th month and it won't let me click on the cell. I click
one more time and it starts me over, erasing the previous 9 cells that I have
clicked on. Anyone know what's going on and how I can fix it?

Nevermind, I ended up doing something different.
