# Equation Editor Issues

My question has to do with symbol function with the Equation Editor.  Recently I tried to recreate a formula that included the summation symbol (sigma sign).  It copied sign just fine, but it does not allow me to add indexes or limits - which would give me blue shaded boxes the same way as fractions, root signs, subscripts and superscripts - - these work fine.  The sigma sign is missing this function so formulas with it are incomplete.

Any suggestions? Thanks!
