⚠️ Common Issues

1. User Permission Format

Issue: User IDs must be stored as comma-separated string

Solution: Always use filter_input with FILTER_REQUIRE_ARRAY and convert to CSV format

2. Empty User Selection

Issue: No users selected causes empty array

Solution: Code includes -1 prefix to handle empty selections

3. Price Validation

Issue: Non-numeric prices can cause issues

Solution: Should add numeric validation on form input
