Decrementing the value of a variable
<p>Is it possible to put this code</p>

<pre><code>$left_Nickels = 20;
</code></pre>

<p>Inside any conditional and decrement the value of $left_Nickles?</p>

<p>Or do I have to initialize to "".</p>

<p>I want to be able to decrement the quantity of 20, which indicates the number of Nickels?</p>

<p>That's why I don't want to start of by initializing to "", and then later on in a conditional
assigning $left_Nickels = 20;</p>

<p>Thank you, for not flaming the newb, but for helping the newb to understand and learn. </p>
