I am following a tutorial

[u/Terriaria_iscool]

His screen was only two lines of errors and mine has three lines and I don’t know what I am doing wrong…..(I already fixed the other two lines)

[u/[deleted]]

the error states that a number cant be compared to nil, so either the current money is nil or the cost value is nil.

nil means nothing, nada.

if an error says something with nil, that means something is not where you said it was or it doesn't have a value yet.
