# ✅ Supplier Payment Total Amount Fix - COMPLETE!

## 🎯 Problem Identified

In the **Supplier Given Payment Multiple** page, the **Total Amount** column was not showing because the code was referencing a non-existent field `booking_supplier_amount`.

### Root Cause
The booking table has these fields:
- ✅ `booking_supplier_subtotal` - Sum of all supplier amounts
- ✅ `booking_supplier_tax` - Supplier tax percentage  
- ✅ `booking_supplier_total` - Final supplier total with tax
- ❌ `booking_supplier_amount` - **DOES NOT EXIST**

The old code was trying to use `booking_supplier_amount` which was never created in the database.

## 🔧 Files Fixed

### 1. **Frontend - SupplierGivenPaymentMultiple.jsx**
**Location:** `src/pages/supplier-given-payments/SupplierGivenPaymentMultiple.jsx`

**Changes:**
- ✅ Line 608: Changed `booking.booking_supplier_amount` → `booking.booking_supplier_total`
- ✅ Line 677: Changed `booking.booking_supplier_amount` → `booking.booking_supplier_total`

**Impact:** Now displays the correct supplier total amount in:
- Table column "Total Amount"
- Summary statistics section

---

### 2. **Backend - SupplierGivenPaymentRequest.php**
**Location:** `app/Http/Requests/SupplierGivenPaymentRequest.php`

**Changes:**
- ✅ Line 45: Changed `$booking->booking_supplier_amount` → `$booking->booking_supplier_total`
- ✅ Line 57-58: Updated comments and variable names

**Impact:** Payment validation now uses correct supplier total field

---

### 3. **Backend - SupplierGivenPaymentResource.php**
**Location:** `app/Http/Resources/SupplierGivenPaymentResource.php`

**Changes:**

### 4. **Backend - SupplierGivenPaymentRepository.php**
**Location:** `app/Repositories/SupplierGivenPaymentRepository.php`

**Changes (Already Fixed Earlier):**
- ✅ `getBookingPaymentSummary()` - Uses `booking_supplier_total`

- ✅ Response key changed from `booking_supplier_amount` to `booking_total`

**Impact:** Payment calculations use correct supplier total

## 📊 Comparison: Agent vs Supplier Payment

### Agent Receivable Payment
- **Field Used:** `booking_total_amount`
- **Calculation:** `booking_subtotal + (booking_subtotal × booking_tax%)`
- **Purpose:** Amount agent needs to pay you

### Supplier Given Payment  
- **Field Used:** `booking_supplier_total`
- **Calculation:** `booking_supplier_subtotal + (booking_supplier_subtotal × booking_supplier_tax%)`
- **Purpose:** Amount you need to pay supplier
