Thanks Chad,
This time i created a textbox with default value and then converted it into hidden field. Then i filled the form and user is now becoming premium users role.
We also want to give the validation period for these premium user role i.e for 6 months user should have this premium role after that it should automatically get expire. Is this requirement is possible using dynamic registration form , if yes then what setting should be set for that OR We should manually delete the users role after 6 months.
Please let me know,
Thanks
Ashok Naidu
