Adding multiple Numbers

Hi there,

I'm building a calculator of sorts and have about 7 input text boxes (input text chosen) that users can enter numbers. At the bottom I have a calculate button that adds all of the numbers users have input into the boxes. The answer goes into a dynamic text box. It all works fine expect if a user does not enter in a number in one or more of the boxes. In other words, users would have to input a number in each box for it to work, I don't want that.

Here is the code on the calculate button:

TransportationTotal = Number(Limo) + Number(SUV) + Number(HorseCarriage) + Number(Boat) + Number(Helicopter) + Number(LuxuryCoach) + Number(LuxuryCar) + Number(TransportationGuests);
}

whereas the names in brackets are the var assigned names. Any ideas? Do I need to declare the var's beforehand? Tired this and did not work.

you could have make code that if the text fields have nothing than the code will give them a value like:
if (Limo == ""){
Limo = "0";
}
Then you wouldn't have to change your above code.

you could also start out with 0's in your text fields...

I would also check to see if textField != "" before adding it to the total..
