# V18.6 - DISTANCE CALCULATION DEBUGGING

## 🎯 **CRITICAL FINDING**

The DISTANCE_MATRIX **IS LOADED CORRECTLY**:
```
✅ Matrix loaded: 114 routes
✅ Key exists: "rochdale->liverpool-airport" → true  
✅ Value: 38 miles
```

But when you submit the form, it shows:
```
❌ [getDistance] Looking up: "rochdale" -> "liverpool-airport"
❌ Trying key1: "rochdale->liverpool-airport"
❌ Not found, fallback to 25 miles
```

##  **POSSIBLE CAUSES**

### 1. **Form Values Have Extra Whitespace**
The form might be sending `" rochdale "` instead of `"rochdale"`.

### 2. **Case Sensitivity Issue**
The form might be sending `"Rochdale"` instead of `"rochdale"`.

### 3. **Scope Issue**
The DISTANCE_MATRIX might not be accessible from inside the submit handler.

## 📋 **TESTING INSTRUCTIONS**

### **Test 1: Check Console at Page Load**

1. Open: https://3000-ibnwdfw71auepqpe8f3p3-b9b802c4.sandbox.novita.ai/quotation.html
2. Open Browser Console (F12)
3. You should see at page load:
   ```
   [MATRIX] DISTANCE_MATRIX loaded with 114 routes
   [MATRIX] Sample key check: "rochdale->liverpool-airport" exists? true
   [MATRIX] Sample value: 38
   ```

**✅ If you see this**: Matrix is loaded correctly!

---

### **Test 2: Submit the Form**

1. Fill in the form:
   - **Pickup Location Type**: Service Area
   - **Pickup Location**: Rochdale  
   - **Dropoff Location Type**: UK Airport
   - **Dropoff Location**: Liverpool Airport
   - Fill in date/time/vehicle

2. Click **"Calculate Fare"**

3. **Check console output**. You should NOW see:
   ```
   === Calculation Start ===
   Pickup: rochdale
   Dropoff: liverpool-airport
   [getDistance] Looking up: "rochdale" -> "liverpool-airport"
   [getDistance] Trying key1: "rochdale->liverpool-airport"
   [getDistance] Key1 value in matrix: 38          ← NEW DEBUG LINE
   [getDistance] Matrix has key1? true              ← NEW DEBUG LINE
   [getDistance] ✅ Found in key1: 38 miles         ← Should work now!
   ```

**Expected Result**: Should show **38 miles** and **£76.00** (at £2/mile)

---

### **Test 3: If Still Shows £50**

If it STILL shows £50, please copy the COMPLETE console output and send it. The new debug lines will tell us:

1. What values are being passed to `getDistance()`
2. What the matrix lookup actually returns
3. Whether the key exists in the matrix at runtime

---

## 🔧 **WHAT I ADDED**

### Debug Output at Page Load:
```javascript
console.log('[MATRIX] DISTANCE_MATRIX loaded with', Object.keys(DISTANCE_MATRIX).length, 'routes');
console.log('[MATRIX] Sample key check: "rochdale->liverpool-airport" exists?', 'rochdale->liverpool-airport' in DISTANCE_MATRIX);
console.log('[MATRIX] Sample value:', DISTANCE_MATRIX['rochdale->liverpool-airport']);
```

### Debug Output in getDistance():
```javascript
console.log(`[getDistance] Key1 value in matrix: ${DISTANCE_MATRIX[key1]}`);
console.log(`[getDistance] Matrix has key1? ${key1 in DISTANCE_MATRIX}`);
```

---

## 🎯 **NEXT STEPS**

1. **Test the form now** with the new debug output
2. **Send me the complete console output** from a form submission
3. The debug lines will reveal exactly where the problem is

---

## 📊 **Current Status**

- ✅ Matrix loads: 114 routes
- ✅ Key exists: "rochdale->liverpool-airport"
- ✅ Value correct: 38 miles
- ❌ Form submission: Shows £50 (25 miles)
- 🔍 Need: Console output from form submission to see what's happening
