This is an English language forum.

I have edited your title but in future please remember to only post in English.

Please edit your post and use the code button (Alt+S) when pasting code.

EDIT your original post, please do not just post the code correctly in a new post.

1. Please edit your (original) post and use the CODE button (or Alt+S)! (For large amounts of code, attach it.)

2. Use the debugger or print out your variables, including _LastError and prices and find out why. Do you really expect us to debug your code for you?
