+ ### :checkered_flag: Problem Explanation:
+```javascript
+function testElseIf(val) {
+  if (val > 10) {
+    return "Greater than 10";
+  }
+
+  if (val < 5) {
+    return "Smaller than 5";
+  }
+
+  return "Between 5 and 10";
+}
+
+// Change this value to test
+testElseIf(7);
+```
+We'll be modifying the existing code above so that it follows the flow of logic that an **else-if** statement has.
+
+ ### :speech_balloon: Hint: 1
+ ``` javascript
+   if (val > 10) {
+    return "Greater than 10";
+  }
+  ```
+  All if statements and their variants start off with an *if statement*
+ try to solve the problem now
+
+ ### :speech_balloon: Hint: 2
+  ``` javascript
+  else if (val < 5) {
+    return "Smaller than 5";
+  }
+  ```
+  Statements between the *if statement* and the *else statement* in an **else-if** flow are in the else-if format
+ try to solve the problem now
+
+ ### :speech_balloon: Hint: 3
+``` javascript
+else {
+  return "Between 5 and 10";
+  }
+ ```
+ The last statement in an **else-if** flow is in the *else* format
+ ### Spoiler Alert!

+ Solution ahead!
+ ## :beginner: Basic Code Solution:
+```javascript
+function testElseIf(val) {
+  if (val > 10) {
+    return "Greater than 10";
+  }
+
+  else if (val < 5) {
+    return "Smaller than 5";
+  }
+
+  else {
+  return "Between 5 and 10";
+  }
+}
+
+// Change this value to test
+testElseIf(7);
+```

+ ## Code Explanation
+The structure of an **else-if logic flow** is an initial *if statement*, one more *if-else statements*, and one final *else statement*
