I am very noob to UiPath and I have not programming background.
I have excel file Keywords where two columns are Keywords and Products
1: I go to a website and in saerch box I use Type Into activity and take data from Column A .
2: when the search results come I want to find the product from Column B and use element exist activity to check the product on current page .
3: if the product is not on current page then go to next page and find product
4: when product found then click on it
5: again search the keyword and repeat the process from step 1 to 4 again.

here is my XAML to check where I am missing
