The calculation of PivotHigh, PivotLow is being assigned a value of 1 or NULL. The NULL is probably the problem. Change the assignment to use 1 or 0 and everything will likely fall into place.
The only reason that I knew what you were talking about is that I ran into the same problem on that same library submission! I don't have my solution in front of me. But, I seem to recall that that was the issue.
