Please. You don't get the asterisk because your group is not required, only one element in the group is required: 'postcode'. The static element is not required and as such, the group as a whole is not marked required. This works: $form->addRule('postcodeGroup', 'this is required', 'required', null, 'client'); $rule[0][0] = array('bad postcode', 'regex', '/[a-zA-Z]{1,2}[0-9][0-9A-Za-z]{0,1} {0,1}[0-9][A-Za-z]{2}/', 'client'); $form->addGroupRule('postcodeGroup', $rule); But by doing so, you are trying to cheat QuickForm because a static element can't be required. The recommended way would be to improve your template to display help (your static element) as a second label. You can use an array for your element label. Have a look at the examples to see how your template should look like. There is also another way, it would be to use a specific template for your group showing its label. If the label is shown and the required block is present in your template, then the label will have the asterisk. Again, study the examples, the block is called qf_table_group or something like that in ITX examples. Bertrand Mansion Mamasam
