Error message when trying to compile - not exactly sure how to fix it

[suprsnipes]

Hi,

I am getting the following error message Operator '-' cannot be applied to operands of type 'string' and 'double' when trying to compile the code below;

Print("S = " + bidPrice - lastPrice  + " Levels");

Appreciate your help,

suprsnipes,

I would suggest doing this :

double temporary = bidPrice - lastPrice;

Print("S = " + temporary + " Levels");

Please let me know if I may assist further.
