Error trapping in Dreamweaver on MySQL table

-

i have relational mysql tables . when user wants delete record tabel via webpage , record has relation table, delete should forbidden.

now error message mysql, want make own message user on webpage. how proceed make possible.

thanks replies.

it sounds printing "mysql_error()" error instead of replacing variable own message.  while putting new error message may solve problem, script should try determine other dependancy user can take action if removal of data ultimate goal.  otherwise left frustration.
