//V.2 Notes: Create global variable clickToggle to toggle between X and 0 upon each click. also blocked JS from updating elements that have already been clicked. Also added more rows/cells so that now there are 36 cells. var clickToggle = 0; function clicked1(){ if(clickToggle == 1){ document.getElementById("td1").innerHTML = "0"; clickToggle += -1; document.getElementById("td1").id = "checked";} else{ document.getElementById("td1").innerHTML = "X";
