How to script if no of pages to be filled will change based on the country selected from dropdown

Hi,

In my current scenario, the no of pages to be filled is changing depending on the country selected

If my selected country is United States,I have to fill 5 pages

If my selected country is United Kingdom I have to fill 6 pages

 

in this scenario

I recorded using United States(5 pages)

I correlated country name and selected Random value because different vusers should select different countries in real time

If any vuser will select United Kingdom,he have to fill six pages and the pages are also changed based on the Country,

How to write script

 

Any help is appreciated
