addFormat with Spreadsheet Excel Writer

Greetings all, Thanks for the help with the Spreadsheet Excel Writer yesterday. I was wondering if anyone knew of problems with the addFormat() within the writer and PHP 5.0. I have followed the examples for setting up a specific format but it is not being recognized. Here is what I have tried... $format_bold =& $workbook->addFormat(); $format_bold->SetBold(); And $title_format =& $workbook->addFormat(array('fontfamily' => 'Arial', 'size' => 13, 'color' => 'black', 'bgcolor' => '#C0C0C0', 'bold' => 1) ); Neither have worked. The error I get is pointing to the Writer/Worksheet.php file, line 1242 indicating that it cannot be converted. Yet, this same code was used in another application that is running PHP 4.2 Jef Sullivan Programmer Progrexion work (801) 828-1745 moble (801) 682-9727 jsullivan@progrexion.com Research | Marketing | Sales Generation This email and its contents are confidential.
