# V7005\. A variable is assigned to itself\.

The analyzer has detected a potential error when a variable is assigned to itself\.

The example:

```cpp
change(width, height, length) {
  this.width = width;
  this.height = height;
  length = length;
}
```

In this method, the fields should receive values from the method parameters with matching names\. However, a typo causes an error: instead of modifying the `length` field, a parameter with the same name is assigned to itself\.

The fixed code:

```cpp
change(width, height, length) {
  this.width = width;
  this.height = height;
  this.length = length;
}
```
