math question 2

[codeone]

hey,
got a simp[le math question, I need to add to values from two different texboxes and I tried like so:

function sumIt(){
var te = document.alpha.a6.value;
var et = document.alpha.a7.value;
var fin = te + et;
document.alpha.l0.value='$'+fin;
}

but it jus concentates it and doesnt add the two values together. How can I make this add the two values?

thanks

co

function sumIt(){
   var te = document.alpha.a6.value * 1;
   var et = document.alpha.a7.value * 1;
   var fin = te + et;
   document.alpha.l0.value='$'+fin;
}

Functionality wise, the above example would yield the correct results (as would subtracting the numbers by 0, or dividing them by 1). However, programmatically it is correct to use parseInt or parseFloat depending on what type of numbers you're dealing with. Looks like you're dealing with currency so parseFloat is probably what you want:

function sumIt(){
   var te = parseFloat(document.alpha.a6.value);
   var et = parseFloat(document.alpha.a7.value);
   var fin = te + et;
   document.alpha.l0.value='$'+fin;
}
