Listing places with arrays. Submit button not functioning properly.

<script>
var places = []; // new array to store entered places
var i = 1; // counter variable to track array indexes

// function to add input to array and then generate list after 5th submission
function processInput() {
places[i] = document.getElementById(“placeBox).value; // add entered value to array
document.getElementById(“placeBox”).value = “” // clear text box
if (i < 5) { // iterate counter variable
i++;
}
else { // add entered value to array and write results to document
document.getElementById(“resultsExpl”).innerHTML = “You entered the following places:”;
listItem = “”;
for (j = 1; j < 6; j++) { // write each array element to its corresponding list item
listItem = “item” + j;
document.getElementById(listItem).innerHTML = places[j];
}

}

// add backward compatible event listener to Submit button
var submitButton = document.getElementById(“button”);
if (submitButton.addEventListener) {
submitButton.addEventListener(“click”, processInput, false);
} else if (submitButton.attachEvent) {
submitButton.attachEvent(“onclick”, processInput);
}

</script>
