Error with math equation
<p>My problem is that if you look at 'support' variable. (In the variable list) it doesn't apply to the  Current Consumption. For EX. If I press 'S' and enter to start the game then press 'M' to display missions then press 'S' to choose the Survivors mission. And I recieve 2 survivors. That count won't add to the support for some reason and display "You are consuming 0.5 blah blah blah" not "You are consuming 0.7 blah blah blah" as it should be adding 0.1 per human? Sorry if this is hard to understand, I'm only 11 trying to program!

<p>You're never updating your <code>support</code> variable after you set it the first time so each time you print it out it's the same.  Since <code>support</code> is dependent on <code>human</code>, you should either recalculate <code>support</code> every time <code>human</code> is updated or have a function like <code>calculate_support()</code> which calculates it when you need it.</p>
