DrawText question

[johne5]

I see drawtext question all the time. so I'm sorry if this has been asked already.
In my example the first DrawText works ok, it draws "Top" above the current bar.
the second example, fails. the error is something about a double can't be converted to a string.
Is there a way to create a string that is the a price? ex: 791.4

protected override void OnBarUpdate()
{
TopPrice = Low[0] + 5 * TickSize; //this is a double

DrawText("Top" + CurrentBar, "Top", 0, Low[0] + 5 * TickSize, Color.SlateBlue);
DrawText("Top" + CurrentBar, TopPrice, 0, Low[0] + 5 * TickSize, Color.SlateBlue);
}

thank you

I got it figured out

DrawText("Top" + CurrentBar, "" + TopPrice, 0, Low[0] + 5 * TickSize, Color.SlateBlue);
