HI, you can use refer the code for your reference. Make sure the submit=false for back and Next buttons. Instead of the pages you can add your respective UI 
 {
 a!localVariables(
 /* List of icons in milestone (stamp) */
 local!milestoneStampIcons: {"plane", "ticket", "shopping-cart", "check"},
 local!currentMilestoneStampStep: 2,
 {
 /* Display stamps */
 
 a!sectionLayout(
 contents: {
 a!cardLayout(
 contents: {
 a!sideBySideLayout(
 items: {
 a!sideBySideItem(),
 a!forEach(
 items: local!milestoneStampIcons,
 expression: if(
 /* If final step is completed */
 and(
 fv!index = local!currentMilestoneStampStep,
 fv!index = length(local!milestoneStampIcons)
 ),
 a!sideBySideItem(
 item: a!stampField(
 icon: fv!item,
 backgroundColor: "ACCENT",
 size: "TINY"
 ),
 width: "MINIMIZE"
 ),
 if(
 /* Completed step so far */
 fv!index < local!currentMilestoneStampStep,
 {
 a!sideBySideItem(
 item: a!stampField(
