However, the row is never inserted.   "something" is always some valid value, but I figured I would spare the parsing code.  The weird thing is though, for debugging, I checked to see what row 0 has in it for it's values after inserting.  They're always zero, and the rows are never there. To boot, the row (or rows) I created in the constructor and had values of "test1, test2, ..." are now set to 0. :(I checked to make sure the address of my tbl_pos was correct, and sure enough it is.  Alas, no rows.*/
