Not if you add a row/column before C13 it won't - Try it ;-) The use of the $
signs make the reference absolute for the purposes of copying and pasting, but
inserting rows/columns prior to that cell will force it to move, and any linked
reference will stay with that cell, unless, you use INDIRECT.
See Niek's use of INDIRECT to lock down a reference that won't be affected by
inserting/deleting Rows/Columns in the other response.
