# 0021: Incorrect variable name

The compiler expects an integer number for [local variable](https://docs.sannybuilder.com/language/data-types/variables#local-variables) names.

**Possible solutions:** use a valid integer number that meets the local variables [limit](https://docs.sannybuilder.com/scm-documentation/gta-limits) for this game:

```
var@s = 'test' // incorrect
0@s = 'test' // correct
```
