I'm a n00b when it comes to PhP and I'm having trouble making a calculator for a game I play. The result I keep getting is wrong, to mirror my results the following will need to be inputted into the infrajump.php file:
Current infra level: 10999.99
Desired infra level: 14999.99
5 factories
check interstate system
check Lumber, Iron, Aluminum, Marble, Construction
check Monarchy, Capitalist, Dictatorship, Federal, Republic or Revolutionary
The result is:
Your current infra level is: 10999.99
Your desired infra level is: 14999.99
To reach 14999.99 you will need to buy 4000 infra, which will cost you 230.
The cost is way beyond wrong it should be in the millions if not billions.
Here is the code....

Current infra level (WITHOUT COMMAS): <input type="text" name="infra" /><br /><br />

I've been over it 6 ways to Sunday and still can't figure out what is wrong. I know it's likely something only a newbie would miss, so thanks in advance to anyone who can spot what I'm doing wrong.
