"won't work" tells us nothing. Next time post the complete text of your error messages.
Anyway, your variables daily,weekly,quaterly,bianually,yearly are not initialised.

[Starstreak]

There are a few things wrong with the program.

(Apart from the variables not being initiated)
(1)
line 34: period = Scanner.nextInt();

The scanner expects an integer value. It isn't clear whether you want input to be a String or an integer. If you need the user to enter "daily", then variable period should be a String. In which case line 34 should look like this:

period = Scanner.next();

(2)
Don't use "Scanner", rather change it to "console" or "sc" to avoid confusion:

line 21: Scanner console = new Scanner(System.in);

(3)
Your interest value is going to get entered as a whole number. This is normally a percent, so for example; 7 % should be 0.07 for the calculation.

See if you can find the other mistakes yourself and come back ;-)

1. Your variables are not initialized.

2. And even if you think you did, with "double", you used them like "Integers"

    primary = Scanner.nextInt();

And also, you shoud try another name instead of Scanner to avoid confusion.
