The function, when called, complains that it expects a parameter of type string. Where does it get the string?

in which line is it swearing? which function call?
I think it's the Ordersend that's swearing.

I think it's the Ordersend that's swearing.

Yes, of course it is. There! 2013.06.16 14:32:49 2010.02.01 08:04 EURUSD,H1: OrderSend error 4062

So what? So what's the strings??????
Anyway, I've got it. I'm either going to remove the entire back of the string braces so they don't get in the way...

Good afternoon! The function, when called, swears that it expects a parameter of type string. Where does it get the string? Actually, I've been using this function for years and it didn't complain. I've just split it in two parts - for buy and for sell.
OrderSend() has the 8th parameter - string, but in my code - double.

OrderSend() has the 7th parameter as string and the code as double.

THE QUESTION IS SIMPLE. I FORGOT SOMETHING WITH EMPTY AND THE LINE SEGMENT GOES "BROKEN". Please suggest what I can't remember))):
