How can I change the "OTHER" option on a question

When asking a single choice question, I provide 3 options, however, I want to give the "OTHER" option as well. 

The end user, however doesn't understand that is is a place for them to actually type their custom "other" option. They want to simply check the mark next to the word "other", but it won't allow you to do that until you actually type something there.

I am trying to find out how to change the word "Other" to something like "Other - Type your information here" so that they understand they MUST type something for this option to work.

To edit your "Other" text,you need to go to your Single Choice properties, OPTIONS

scroll down until you find Display other Option and input your desired text.

Now we, need to add your css to place the info clearly.

#input_1{
  display: block;
  width: 200px;
    margin-top: -20px;
    margin-left: 20px;
}
