Ok, I was trying to keep it simple :), but here goes:
In essence the problem is that (at the end of the script)
income_out is coming out as just $option_close_price and not the
intended $option_close_price*$no_sold, and
profit_loss is coming out as just -$option_close_price and not the
intended $income_in-$option_close_price*$no_sold.

Justin,
Is the code you posted all of the code or just a small snippet? You
don't appear to be setting $C or $G. Could you post a larger code dump
please?
