I am having an issue with validation rules on Choice controls. I have two choice controls. The second choice control needs to become mandatory or required once a particular value is selected from the first choice control. The first choice control is a drop down list with the selection values of One, Two, Three. If Two is selected from the first choice control, the second choice control has a validation rule to force it to be selected. This validation rule is not working when assigned to the choice control. If I place a text box on the form and assign the same validation rule, it does error on submit if Two is selected from the first control.
