Hello CB,
See, i insert the new field name 'Register' in the CB register form, is unique and number, then the new user complete the form, and compare the field value 'Register' with the field name of the database, if the value is duplicated, show the JS Alert 'Error: The number of Register is duplicated', and this logically should stop, but, the fields (id,name,username, password, ...) is inserted in the table 'jos_users' and the another table 'jos_comprofiler' is not inserted.
The idea is that, if the field value 'Register' is duplicated, this must stop and do not insertar the values in the table 'jos_users'.
Thanks,
