1527763586000 represents the ID of the zip:

Create a constant called chevronZipID with value of 1527763586000

Go to your Flow.
Create four stages. Name them stage 1, stage 2, stage 3
NOTE: Set each stage active
Create a variable called stepNumber with the default value to 0.
Create three screens.
On the first screen add a display enter the text. The image contains a link which sets the stepNumber parameter.

Note: There must be No Whitespace:

On the first screen add a display enter the text:

On the third screen add a display Field and enter the following default value:

You can flow through the flow using the default buttons. However, you can also click on the different step images of the flow.

Decision Element 1: Checks stepNumber.
If 1 go to Assignment (Set {!$Flow.CurrentStage} = {!stage_1} And a flow to Screen 1

Else go to Decision Element 2
Decision Element 2: Checks stepNumber.
If 2 go to Assignment (Set {!$Flow.CurrentStage} = {!stage_2} And a flow to Screen 2
Else go to Decision Element 3
Decision Element 3: Checks stepNumber.
If 3 go to Assignment (Set {!$Flow.CurrentStage} = {!stage_3} And a flow to Screen 3
Else go to Assignment (Set {!$Flow.CurrentStage} = {!stage_1} And a flow to Screen 1
Stage 4: After Screen 3 there is one more Screen. This screen shows a summary.
Create an Assignment (after screen 3) that assigns the current stage to (Set {!$Flow.CurrentStage} = {!stage_4} And a flow to Screen 4.
Create a Screen with a summary of the info gathered.

Hi Arun , Step Number is a variable that needs to be created here and I hope you havent confused that with the steps of flows. Also make sure that the default value of the step number to be 0.

Thank you for posting this article. I am stuck at how the navigation between the pages is done depending on the stepNumber you have used. It would be great if you could give an insight on how to leverage the stepNumber to render the pages.
