hey i'm having problem implementing registration page using mysql database. when insert ' namespace localhost_54355 ' in page's code, buttons, text boxes, panels, not recognized. when remove 'namespace', buttons becoming available class dbroutines not recognized. can me identify problem?

thanks!

note: variables here ' dbroutines.insert.addcompany(textusername.text, txtco_jobposition.text, txtco_jobpositiondescription.text, txtco_email.text, int.parse(txtco_phone.text), txtco_address.text); ' not correct. correct 1 'textusername.text' it's still recognized when remove 'namespace'.
