I tried using your code but nothing happens I don't understand why you are using "body"backgroundColor = "1". In order to change the color of the background you use document.bgColor = "(your color goes here)";

The structure of your function should be a follows

<script>
    function backgroundColor()
    {
        // create a variable
        if(/*variable is true*/)
        {
            document.bgColor = /*(your color goes here)*/;
        }
        else
        {
            document.bgColor = /*(your new color goes here)*/;
        }

    }
</script>

Now to get the paragraph text to change color you use the document function such as the getElementByID. To give you a clue for your variable being true/false think of it mathematically.

Example:

variable = 1 is true

variable = 0 is false

Hope this helps

Okay this is what i think is your issue however I am not sure. The issue with your function is that in the if statement you are stating that if the body and div tags are a certain color than change them to another color. To my knowledge with if statements is that in the condition you compare

For instance,

var number = 5;

if(number == 5) {document.getElementByID("style").style.backgroundColor = "red";}

This is how I would approach the condition.

One major difference between = and == is that one is assigning and the other is comparing

For example,

var number = 5; the variable number is now assigned 5, meaning it has a value of 5

if (number == 5) {} the variable is being compared to 5 

if(5 == 5 ) {} true

In your code in the if statement your are assigning the id element to blue and div element to red. Not necessarily a condition.

I tried approaching it with your condition but I did not get anywhere. I hope this helps and good luck.

It should fix your issue assuming your default colors are blue for body and red for div

otherwise change it to this and it should work

if((document.getElementById("body").style.backgroundColor == "white") &&
        (document.getElementById("div").style.backgroundColor == "black"))

No problem. Glad to help. 

Also, in reference to your CS122 forum an alternative to logging in to MySQL is as follows:

By using your spotlight you can access MySQL server. it will open the MySQL server on the system preferences. Here you can start/stop the server without having to enter the sudo command. After that everything else is the same as NBTANG stated.

Goodluck
