How to add total price in a cart php -

Hello, I'm currently making a project for assignments to create a website that sells games, so far everything is fine On the issue of linking the shopping cart's totals. Below is a PHP part of the cart file that shows every game and puts the price of the game every time it carts.

The only value I get is 0.

I query this php file at the top of this file

   Query ($ query); $ numrow = $ results- & gt; num_rows; ? & Gt;   
 I'm not sure why this code is not working:  
  $ i = 0; While ($ count & lt; $ numrow) {$ i = $ gamePrice * $ quantity; } echo $ i;   
  Cart.php   
  & lt ;? Php $ count = 0; While ($ count & lt; $ numrow) {$ row = $ result - & gt; Fetch_assoc (); Extract ($ line); Echo "& lt; div & gt;"; Echo "& lt; div class = 'recommended_games' & gt;"; Echo "& lt; img src = 'picture />. GameIMG.' '/'> "; Echo" & lt; / div> "echo" div class = "price_tag"> gt; echo '& lt; div class = "price_tag" name = "price" method = "POST" & gt; one pound.  'echo'   gt; 3 & lt; echo '& lt; option value = "4"> 4 ; echo' & lt; option value = "5" & 5  '; Echo' '& lt; / select & gt;'; Echo '& lt; input type = "hidden" value = "'. $ gameID '' name = "gameid" id = "gameid" /> & quot; echo '& quot; input type = "submit" value = "update" /> gt; echo & lt; / form & gt;'; Echo '& lt; div class = "quantity_update" & gt;' echo '& lt; form action = "remove_item.php" method = "POST" & gt;' echo '& lt; input type = "hidden" Value = "' $ gameID '' name = "gameid" id = "gameid" /> gt; echo '& lt; input type = "submit" value = "remove item" />' echo & lt; / form & gt; ; '; Echo & lt; / div & gt;'; echo & lt; / div & gt; '; echo' '& lt; Img class = 'box1' src = 'Images / Gray-Banners page' / & gt; "echo" & lt; & lt; div id = "delete_all" & gt; & quot; echo '& quot; form action = "delete_cart.php" method = "post" & quot; div / gt; & quot; $ count = $ count + 1; gt; 'echo' & lt; input id = "hide_button" type = "submit" value = "clear all" />; '; echo' & lt; / form & gt; '; echo & lt; / div' & gt; 'echo' & lt; div id = "totalprice" & gt; 'echo' form form = "order_items.php" method = "post" & gt; 'echo' & lt; input Type = "submit" value = "confirm item" />, 'echo & lt; / form & gt;'; echo & lt; / div & gt; 'echo' & lt; div id = totalprice2 & gt; ; $ I = 0; while ($ count & lt; $ numrow) {$ i = $ gamePrice * $ quantity;} echo $ i; echo & lt; / div & gt; ';? & Gt;    
 
 
 You are not looping through here:  
  $ I = 0; while ($ count & lt; $ numrow) {$ i = $ gamePrice * $ quantity;} echo $ i; // Add this $ i ++
