 You should fix the capitalization error in the `math.random()` line. 
 
 ```js
-assert.match(getRandomIndex.toString(), /\s*darkColorsArr\.length\s*\*\s*Math\.random\(\s*\)\s*/);
+assert.match(getRandomIndex.toString(), /\s*(darkColorsArr\.length\s*\*\s*Math\.random\(\s*\)|Math\.random\(\s*\)\s*\*\s*darkColorsArr\.length)\s*/);
 ```
 
 You should round `darkColorsArr.length * Math.random()` down to the nearest whole number.
