Can you show me why OrderDelete() do not work. Thank pro!!

What is the error code is Print() returning?

If the orders are not being deleted and you are not getting an error report then the problem is in the previous code that calls the Dong function

I can't follow your code at all because it is too much work to try to work out what the variables are because the variable names give no clue.

Probably because k is a double . . . does it need to be ? why can't it be an int ? have you read and understood this ? Can price != price ?

It return "Err=0";

Do you know for a fact that the OrderDelete() is actually being called ?
