ImportHTML

I'm trying to pull information from a website using the importhtml function:


And it works, but there's a spot on the web site to search a zip code...How can i factor that zip code into the formula?
When i click search on the zip code, the website url stays the same...

Please message me, I cannot paste the URL website into the thread as I need to post a few times on the forum..

Morning all, anyone able to assist?

newjerseygasprices.com/GasPriceSearch.aspx is the website...

anyone i can add a populated search function for a certain zip code into the importhtml ??

Still looking to see if there's a way to figure this out...
