Well, the problem with setting the variable value in the screenshots is that you are missing the percentage symbols around the value and you're also using the current row in a way that is not something PAD would ever understand.
You already have the %CurrentItem% variable that contains a data row with only the current row. So, use %CurrentItem[0]% to get the value from column 1, %CurrentItem[1]% to get it for column 2, etc.
But since I noticed you mentioned your URLs are not being extracted correctly (possibly because they're not there in the first place), and you need to click on them, I suggest reading the following article on using variables in selectors: https://learn.microsoft.com/en-us/power-automate/desktop-flows/build-custom-selectors#use-variables-in-a-custom-selector
