If you want your rule to run Only when the form loads - check the Initialization Only checkbox at the top of the wizard. Typically, you would check this if there is some business logic that you want to execute before the form/workflow displays and users begin interacting with it.
When the rule displays in the Rule Builder tab, it will indicate that the rule has been flagged to run only when the form loads, if this checkbox is checked. 
Rule Builder Wizards
The Rule Builder walks you through three easy steps to define your condition and actions.
Condition wizard
...
The left side Field and right side Value must be of a matching type. For example, you cannot use numeric expressions with text controls. If you've selected an incompatible value type, Help Mode will show an error to help you correct it.
Builtin Functions
...
The following functions are available in the Rule Builder for building expressions. Function names may be entered in any case (case insensitive).
Functions are entered into the Enter an Expression field in the wizards.
This field has two modes:
...
Lookup Mode is triggered as you enter text in the Value fields of the wizards.

Declare the actions that should be taken when the condition is false. The Functions/Operators listed above can also be selected as the value in this wizard. Else Actions are optional as not all rules require them. You cannot add FALSE actions if you do not have a condition specified in the rule.
Add A Rule
- Click the Run Builder button.
- Click the Add Condition button to create a new condition (optional).
- Select your Field or select current step to describe an action that will execute based on the workflow step currently executing.
- Select the Action from the dropdown.
Select the Value, expression or function(optional). To enter a text value, slide the
toggle switch icon to the right and a field displays to the right.
Info If current step is selected as the condition for a workflow designed using Linked Steps, the value dropdown displays the names of the linked steps as choices. Workflows designed with individual forms as steps (not linked) will only show that step in the current step value dropdown.
For example,
- If you have one form (named form A) in a workflow, you will only see form A listed in the current step value dropdown,
- If you add 2 linked steps (named form B and form C), the current step value dropdown lists all 3 steps: form A, form B and form C.
- If you add form D (not linked) to the workflow, form D will not be listed in the current step value dropdown for form A

A Travel Request workflow contains a field where the user selects a destination country from a dropdown. Countries that call their subdivisions "states" are: United States, Mexico, Australia, Brazil, India, Germany and Myanmar. The business requirement for this rule is: If any of these countries are selected, a Destination State field is enabled so the user can enter the Destination state. Otherwise, the Destination State field is disabled. The Condition wizard for the business rule is shown in the image. Note that each condition is assigned a color coded number that is reflected in the logic expression. The logic expression is built with the and operator by default. Since we want the rule to execute when any of the conditions are true, we must change all the and operations in the logic expression to the or operation.
