Check that the SET ACTION on all your buttons are correct.Speaking of buttons, check all your buttons to make sure the set action is correct. If you just have a sales page and want the button to take people to the next page, you choose NEXT STEP. But, if you are taking information from people (email opt-ins or contact info), the action must be set to SUBMIT FORM. Then it will automatically send them to the next step in the funnel. There are also actions to show/hide elements, take people to certain spots on a page, and the option to write in a custom link.
In professional diving, checklists are used in the preparation of equipment for a dive, and to ensure that the diver and life support systems are fully prepared before they enter the water. To a lesser extent, checklists are used by a minority of recreational divers, and by a larger proportion of technical divers during pre-dive checks. Studies have shown checklists to be effective at reducing the number of errors and consequent incidents.
