how to perform click activity for page no 6 7 8 9 so on?
Your best bet is to follow the screen scraping wizard and choose the Next selector as the Next button, rather than getting numbers 6 7 8 9 etc. This will cause the process to press the Next button until the specified number of records have been gathered, or until there are no more pages.
The problem is every page having 20 url and i have to click every url one by one for all the page.
my work is not to scrap the data
In that case, use an Element Exists to check if the Next button is available and clickable. If it’s not, you can stop iteration, but otherwise, keep clicking that Next button.
