Thomas,
The answer to your problems is the parseInt() function, e.g.
var total =3D parseInt(formname.field1name.value) + =
parseInt(formname.field2name.value);
Form data is treated as strings unless you specify otherwise.
Cheers,
Peter

Hello all!
I am trying to create a form that uses client-side Javascript to sum =
numerical data.
The form has six blanks where numbers are entered. The seventh box =
will display the mathematical total of the numbers entered in the six =
boxes. So far, I can only get the 7th box to either add the html tags =
together (not what I want) or compile the numbers in the box (if the =
first six contain 1,2,3,4,5,6... I get 123456 in the Total box). Any =
ideas, before I pull all my hair out?
Sincerely,
Thomas McCoy
