SCSS conditionals

Hello everybody,

I'm creating a style and I'd like to compare 2 variables, I don't how to do it and all my attempts have produced an error. I'm not sure about the syntax either:

$defaultValue = 100px; // default value
$randomValue = 120px; // This can be any value

@if ($randomValue > $defaultValue) {
    $defaultValue = $randomValue + $anotherVariable;
}

Regards

Solved by using colon : instead of equal sign = to assign the new value to the variable.
