openDatabase Hello World - 2
This is a continuation from a previous stackoverflow question. I've renamed some variables so that I can tell what are keywords and what are names that I can control.
Q: Why is the deleteRow function not working?

You needed to declare the dbo variable outside of the OnLoadCallback function. Also, more currently you would have to update the syntax for the openDatabase call.
I guess no one's going to answer this question, so I'll close it out.
