'ObjectSetText' - declaration without type dtext.mq4 26 4

Tutorial from here http://docs.mql4.com/objects/objectsettext

Can someone help?

Thanks
ObjectSetText(...) function is only the last part of the text displaying.

You must create it first with ObjectCreate(...) function.

int start() expects an integer to be returned. As you don't return a value you get the warning not all control paths return a value

You create a label, but you don't give it any x, y co-ordinates to place it on the chart
