# 0048: Error reading array size

The size of an [array](https://docs.sannybuilder.com/language/data-types/arrays) is missing or is not a number (e.g. a [string literal](https://docs.sannybuilder.com/language/data-types#string-literals)).

**Possible solutions:** use a valid positive number greater than 0:

```
0@(1@,i) = 0 // error
0@(1@,"1"i) = 0 // error
0@(1@,1i) = 0 // OK
```
