# 0045: Invalid array syntax: variable name is missing

The [array](/language/data-types/arrays.md#general-syntax) element is missing either the name or the index [variable](/language/data-types/variables.md).

**Possible solutions:** check the array syntax and provide all required variables:

```
($index,2i) = 0 // error
$array(,2i) = 0 // error
$array($index,2i) = 0 // OK
```
