I am sending email from a system using Nigel Coates' sendmail class and am getting the following error message - VFP Error:107:sendmail:136. It is an operator/operand mismatch. I just can't tell what line of code it happens on because I can not duplicate in my office. This is happening at the client and it does not happen on each computer using the system. It works for me (using XP and Outlook 2003), but blows up on a workstation at the client with the same configuration. Any ideas what could be causing this error?

Thanks,
Doug
