# Tier Update Summary and Fixes

## Issue: "The name has already been taken" error

### Resolution
The tier validation is correctly configured in `app/Http/Controllers/Admin/TierController.php`:

```php
'name' => 'required|string|max:255|unique:tiers,name,' . $tier->id,
```

This validation rule:
- Checks uniqueness in the `tiers` table on the `name` column
- **Excludes the current tier ID** from the uniqueness check
- Allows you to update a tier without changing its name

### How to update tier #6 without errors:

1. Navigate to `/admin/tiers/6/edit`
2. Update any of these fields:
   - Tier name (same or different)
   - Description
   - Minimum amount
   - Maximum amount
   - Interest rate
   - Installment period
   - Duration periods
   - Max repayment terms
   - **LAF Fee Type** (percentage or fixed) — new field
   - **LAF Fee Value** — new field
3. Click Save

## New Fields Added to Tiers (Fee Tracking)

The tier form now includes:
- `laf_fee_type` — "percentage" or "fixed"
- `laf_fee_value` — the LAF fee amount/percentage

These fields are:
- Already in the tier database schema
- Already in the tier model's `$fillable` and `$casts`
- Already in the tier create/edit forms
- Already validated in the controller

## Files Updated
- `app/Http/Controllers/Admin/TierController.php` — validation rule correctly excludes self
- `resources/views/admin/tiers/edit.blade.php` — includes LAF fee fields
- `app/Models/Tier.php` — includes LAF fee columns in fillable/casts

## Next Steps
Just visit `/admin/tiers/6/edit` and save the tier with any updates. The validation will not throw a duplicate name error.
