Without knowing what the code says, it's difficult to say for sure. But my guess is that you've put "=" somewhere where you meant to put "==", or vice versa. "=" sets a variable to a given value, whereas "==" is a way of comparing it to check if it's equal. For example,
This would set the local variable "cowinparachute" with the value of "handsome".
This would check that the local variable "cowinparachute" is equal to "handsome".
The error message that comes up should also come with a number before it. This is the line number where the error takes place. Look it up, and you should be able to fix it pretty quickly.
