I have sheets N1-N23. The final sheet i have created is a summary sheet
where i would like to compile info from N1-N23. I would like to have the
info from cell F15 from each sheet displayed in a column on my summary sheet.
In my summary sheet i have ='N1'!F15. I would like to drag and copy this
formula down my column and have F15 remain constant and N1 to change to N2 to
N3 etc until N23. I can't seem to get it to work?

Any advice or source for advice would be helpful.
thanks
