There are free lisp routines that can sum numbers in text.  Try an Internet search or visit The Swamp and/or Cadalyst magazine on line (look in the CAD Tips area).When you visit The Swamp look for alanjt's thread called Combinevalues.  It contains a lisp routine that will Add, Divide, Multiple or Subtract object values.  CombineValues.lsp v1.2  Copyright 04-09-10 Alan J.
