30 - gold is not the same as having the new value of gold be 30 less than the previous value

4

So, what’s the previous value. Thanks.

5

the previous value is the value of gold before the line execute

but consider that the previous value is 100, what happens in your line of code? what is the new value assigned to gold?

6

The instructions also state:

Similar to your buyHealth function

I would check out that function and use a similar approach
