easiest way to update item pricing after changing discount percentages on a Price List Code?

SOLVED

Sorry if this is a dumb question -- I'm just starting to learn I/C and O/E.  I don't see an obvious way to update prices on items if I make changes to the discount percentages for A-E on the Price List Code which those items are assigned to.    Update Item Pricing would seem to be the obvious answer but that doesn't seem to work.  Thanks for any help.
