Hi, When two users enter their login name & password and press enter simultaniously,the first who entered among the two gets the following error. Error Type: SyntaxError Error Value: unexpected token sequence.near :: 'of_que\012from noq'*'' ******************************* current state = 277 expects: '*', ';', ')', 'ORDER', ('nomatch1',) current token = ((-6, 'FROM'), 'FROM') The above error is while entering the Zope .Again If they fill the form & click submit button simultaniously.The following error occurs for the user who presses submit button first. Error Type: SyntaxError Error Value: unexpected token sequence.near :: "\012Q_name = 'q24'"*'' ******************************* current state = 231 expects: 'EXCEPT', '+', ')', 'HAVING', '-', 'UNION', 'AND', 'GROUP', '*', ';', 'OR', 'ORDER', 'INTERSECT', ('nomatch1',) current token = ((-6, 'WHERE'), 'WHERE') Both users will be accessing the same database. I don't know why this error occurs.If we refresh the error occurred page then it doesn't give error(that time no other user was pressing submit button). In the product which i have implemented multiple users will enter & fill the forms simultaneously. waiting for your immediate reply. bye, jacintha
