## 🐛 Issue

After renaming the return variable from `needsUpdate` to `updateNeeded` in `checkUpkeep()`, the code inside the function was still trying to assign to the old variable name `needsUpdate`.

**Error**:
```
Error (7576): Undeclared identifier. Did you mean "_needsUpdate" or "needsUpdate"?
   --> contracts/reserve/PriceFeedKeeper.sol:104:13:
    |
104 |             needsUpdate = true;
    |             ^^^^^^^^^^^
```

## ✅ Fix

Changed assignments from `needsUpdate` to `updateNeeded`:

```solidity
// Before
needsUpdate = true;
needsUpdate = false;

// After
updateNeeded = true;
updateNeeded = false;
```
