Then i have done Data Scrapping and that you aware of i think
Then Lookup Datatable to find the index(Number of the row)
If condition to check if the datatble has the row available in the Datatable
Assign RowIndex+1 because normaly lookupdatatble will leave the headers while it giving you the index so if we use without incrementing it will be selecting the before one
Click activity and used Dynamic Selectors with idx attribute
