# FIX-197 — Controlled input null value in admin POS Field component

## Fix
`Field` component in `admin/src/app/(dashboard)/pos/page.tsx` passed `value` directly to `<input>`. When parent passes `null`/`undefined`, React warns.

Changed `value={value}` → `value={value ?? ""}`.

## Verification
- `npx tsc --noEmit` (admin): 0 errors
