i was afraid of that... I am going to erase every scribble on the page and start fresh - perhaps get a new perspective. I think I am trying too hard - overthinking it. This is the first one that has totally stumped me even with all these hints!!
I GOT IT!!! I knew my 2nd number was "iffy" (I just couldn't hear the number and associate it with the waveform) so I had to proceed with a process of elimination strategy for that one. It paid off. Thanks for your help!
