    The code will posted doesn't work, The conclusion I have is that the checksum function in that code is wrong or invalid. Ayone willing to share a working php script that checks PR, I need this to finish my directory submission tracker tool.

    that code impliments the checkvalue that was used in versions of the tool bar before version 2.0.114 and was changed in that version and ones after this.

    It also was not authored by Raistlin Majere, all they seem to have done is wrap it in some html from the original version.
