It looks like you need to assign the length of the array (arrayName.length) to the variable 'numberofFrogs'. In this case you don't need a random generator:

int NumberOfFrogs = arrayName.length;  //replace arrayName with whatever variable you're using for the array

thanks this helped me on a different code challenge. I was making it too complicated with parentheses and/or quotes, when it was really just as simple as arrayName.length !
