[Ellerton]

how do you edit it?

[Tony]

editing is disabled. Just follow up on this thread.

[Ellerton]

i am trying to achieve a counter on my code

counter keeps giving an error

i have tried all that i know of

[Tony]

what kind of an error? That is, what does the error say? Is there a specific line of code associated with that error?

[Ellerton]

It Keeps saying counter has no variable

[Tony]

no variable? Are you sure it doesn't say "no value"? You must assign an initial value before a variable can be used. E.g.

code:

var count : int put count

What would the put statement print? It's undefined, so that's an error.

[evildaddy911]

line 90-91 of his code:

var counter : int
counter := 0

that's the only time he declares a variable called "counter", and it's a global variable so there shouldn't be an error

EDIT
just ran the code; "counter" has no problem. however, "score" does. simply do as tony just did and youll be fine

[Ellerton]

i fixed it yester day but i need the score to go up by ten each time the snake eats the food
