# 0074: Disabled option

The compiler finds a [conditional statement](https://docs.sannybuilder.com/language/control-flow/conditions) with a logical operator (**AND** or **OR**) but the required `Check conditions` [option](https://docs.sannybuilder.com/editor/options/general#check-conditions) is turned off. Using logical operators is only allowed when this option is enabled.

**Possible solutions:** enable `Check conditions` in the [options](https://docs.sannybuilder.com/editor/options/general) or replace the operator with an [appropriate](https://docs.sannybuilder.com/language/control-flow/conditions#low-level-if-statements) integer number:

```
if and    // error, option disabled
    0@ == 1
    1@ == 1
then
    //
end

if 1    // OK
    0@ == 1
    1@ == 1
then
    //
end
```
