I am in the process of making level 1 more self explanatory, but in the meantime, I can give you some pointers. Entering the correct statement will solve that box, no need to press enter or anything. After getting the correct answer for the part, a sound should play. If the words turn black, there is nothing to do with them just yet. If they turn white, you still need to edit them (The third box needs to be changed 3 times if I remember correctly). Also, uppercase/lower case doesn't matter.
