+Here’s the setup:
+
+```javascript
+// Example
+// Example
+var ourArr = [ 9, 10, 11, 12];
+var ourTotal = 0;
+
+for (var i = 0; i < ourArr.length; i++) {
+  ourTotal += ourArr[i];
+}
+
+// Setup
+var myArr = [ 2, 3, 4, 5, 6];
+
+// Only change code below this line
+```
+
+We need to declare and initialize a variable ```total``` to ```0```. Use a ```for``` loop to add the value of each element of the ```myArr``` array to ```total```.
+
+We start from declare a variable ```total```:
+
+```javascript
+
+// Only change code below this line
+var total = 0;
+```
+
+Next, we need to use a ```for``` loop to add the value of each element of the ```myArr``` array to ```total```:
+
+```javascript
+for (var i = 0; i < myArr.length; i++) {
+
+}
+```
+
+Now we need to add each value of ```myArr``` to variable ```total```:
+
+```javascript
+for (var i = 0; i < myArr.length; i++) {
+  total +=myArr[i];
+}
+```
+
+ Here’s a full solution:
+
+```javascript
+// Example
+var ourArr = [ 9, 10, 11, 12];
+var ourTotal = 0;
+
+for (var i = 0; i < ourArr.length; i++) {
+  ourTotal += ourArr[i];
+}
+// Setup
+var myArr = [ 2, 3, 4, 5, 6];
+// Only change code below this line
+var total = 0;
+for (var i = 0; i < myArr.length; i++) {
+  total +=myArr[i];
+}
+```
