One column has one letter in each cell, something between A through E,
basically randomly occuring down
the entire column. Next to each cell in that column is a number value
associated with the letter, but of course each nominal letter (not each
instance) may be associated with x different numbers/values, depending
on how many times is shows up in the column. ANyway, how do I use "IF,
then" statements to sum, say, all the numbers associated with "A"?
