I know I've been silent for awhile, finals came around the same time I was
also attempting to get help resolving this.
It wasn't that I lost interest, I just had other things to focus on. I
understand that it probably wasn't in my best interest to go silent if I
wanted to fix this.
I'm still interested in fixing this. Is anyone still willing to help?
