form set_value() not working ,,,,

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
