update: I found my mistake... forgot to include the BI for the balance I had put inside in Feb... (took most of it out to park @ EGA).hmm my Dec-Feb bonus didn't quite add up, differ by a few dollars ($8+)
... not that I'm complaining that I got more than I expected. but couldn't find anything wrong with my formula.
you guys amount tallied?
now it tallies... to the exact cents
thanks CIMB, wish you continued with the bonus interest promo... alas.
