You need to be storing these individual values into numeric variables to be calculated at the end.

thanks this solved it!

Or you can use Integer.Parse() (or Double.Parse(), etc) at that line where you add all the numbers. Maybe add some exception around it, too, .Parse() is pretty picky and throws exceptions when it doesn't get what it wants.

thank you for your help!

You should use integer.TryParse() or decimal.TryParse() instead of handling the exception. Throwing exceptions is a very expensive process and if you have exceptions being thrown in calculations (where it can occur over and over in loops) it can bring a system to a halt depending on the amount of data.

thank you

TryParse is much better than Parse (unless you want exceptions I suppose) . My current job is in .Net 1.1, and I don't get to use TryParse, so I forgot about it. Yes, I do cry a little inside.

mikiurban are you saying to do decTotal = decBasePrice + decEnginePrice + decInterior + decRadio + decShippingCharge + decDealerCharge
Console.WriteLine("The total selling price for your vehicle is $" + Integer.Parse(decTotal))
I tried integer.parse() and parse.() neither worked

sknake i tried that and its saying "overload resolution failed because no accessible 'TryParse' accepts this number of arguments

Cast with the "CInt" function

jbennet i'm new to programming and what am i supposed to do with "CInt"???
