Hi,
set_value() is part of form validation.
If your value comes from controller, just use:
$brand_name;
Once your form has been processed and in case there are errors in the form, then you can use set_value('value_name') which will be 're-filled' on page reload.
Read the form validation in user manual.
Cheers,
Smilie
