The reason for this is these fields are regarded as text and unless you specify number(variable) it may treat it as text.. When Field1='0' Field2='1' Field3='2'
Field1+Field2+Field3 = '012' If you use Field1=Number('0') Field2=Number('1') Field3=Number('2') Field1+field2+field3 = 3 Cheers Simon -----Original Message----- From: Ignatius Reilly [mailto:[EMAIL PROTECTED]] Sent: 11 October 2002 15:48 To: Shahmat Dahlan; [EMAIL PROTECTED] Subject: Re: [PHP-DB] Javascript I have met this problem before.
