+# Accessibility Fix Summary - Issue #160
+
+## Overview
+This document summarizes the work completed to add aria-describedby attributes to form error messages, ensuring WCAG 2.1 Level A compliance for error identification.
+
+## Issue Details
+- **Issue Number**: #160
+- **Title**: Add aria-describedby for form error messages
+- **Priority**: Accessibility compliance
+- **WCAG Violation**: 2.1 Level A (3.3.1 Error Identification)
+
+## Problem Statement
+Form inputs throughout the application lacked proper ARIA attributes linking error messages to their associated input fields. This created significant accessibility barriers for screen reader users who might miss critical error messages, preventing them from successfully completing forms.
+
+## Solution Implemented
+Added comprehensive ARIA attributes to all form components:
+- `aria-describedby` linking inputs to error messages
+- `aria-invalid` indicating error state
+- `role="alert"` for immediate error announcement
+- `role="status"` for success messages
+- Proper label association using `htmlFor`
+
+## Components Fixed
+
+### 1. MobileFormInput.tsx
+- Added unique ID generation for inputs
+- Implemented aria-describedby for error and helper text
+- Added aria-invalid state management
+- Associated labels with inputs
+
+### 2. QuestionForm.tsx
+- Fixed question textarea field
+- Fixed category select field
+- Fixed duration selection with proper group labeling
+- Added proper label associations
+
+### 3. CreateProposalModal.tsx
+- Fixed title input field
+- Fixed description textarea field
+- Added shared error message linking
+
+### 4. RoleAssignmentUI.tsx
+- Fixed userId input field
+- Fixed roleId select field
+- Added role attributes to messages
+
+### 5. MarketForm.tsx
+- Fixed question textarea field
+- Fixed category selection with radiogroup role
+- Fixed duration selection with radiogroup role
+- Fixed custom duration input
+- Added keyboard navigation support
+
+### 6. KYCVerificationForm.tsx
+- Added role alert to error messages
+
+### 7. ResourceAccessManager.tsx
+- Fixed userId input field
+- Fixed resourceId input field
+- Fixed accessType select field
+
+### 8. MultiTradePage.tsx
+- Fixed stake amount input field
+- Added proper error message linking
+
+### 9. CreateMultiMarketPage.tsx

+
+2. **aria-describedby**: Links input to error message
+   - References error message ID when error exists
+   - Undefined when no error (attribute removed)
+
+3. **role="alert"**: Announces errors immediately
+   - Applied to all error message containers
+   - Ensures screen readers announce errors
+
+4. **role="status"**: Announces status updates
+   - Applied to success messages
+   - Non-intrusive announcements
+
+5. **role="radiogroup"**: Groups related controls
+   - Applied to category and duration selections
+   - Improves navigation for screen readers
+
+### Label Association
+- All labels use `htmlFor` attribute
+- Proper association with form controls
+- Improved click targets
+
+### Keyboard Navigation

+## WCAG Compliance Achieved
+
+### Before
+- ❌ Error messages not programmatically associated with inputs
+- ❌ Screen readers could not identify which field had errors
+- ❌ No indication of invalid state for assistive technologies
+- ❌ Failed WCAG 2.1 Level A - 3.3.1 Error Identification
+
+### After
+- ✅ All error messages linked to inputs via aria-describedby
+- ✅ Screen readers announce errors when focus moves to field
+- ✅ aria-invalid properly indicates validation state
+- ✅ role="alert" ensures immediate error announcement
+- ✅ Meets WCAG 2.1 Level A - 3.3.1 Error Identification
+
+## Testing Recommendations
+
+### Screen Reader Testing
+- NVDA (Windows): Verify error announcements
+- JAWS (Windows): Test field navigation
+- VoiceOver (macOS/iOS): Confirm error association
+- TalkBack (Android): Validate mobile experience
+
+### Keyboard Navigation Testing
+- Tab through all form fields
+- Verify focus indicators
+- Test Enter/Space on custom controls
+- Confirm error messages are announced
+
+### Validation Testing
+- Trigger validation errors
+- Verify aria-invalid updates
+- Confirm error message association
+- Test error clearing on correction
+
+## Browser Support
+- Chrome/Edge 80+
+- Firefox 75+
+- Safari 13+
+- All modern screen readers
+
+## Impact
