What should i change so i can use minutes?
That seems a strange question in response to Reply #10 where i recommended that you should NOT use minutes.
And here have been several other Replies that you appear to have ignored - that does not encourage people to help you. If you don't understand something then say so.
If you have made changes to your code to take account of the Replies then you should post the latest version of your program so we can see what you have done and how it compares to your earlier version.
