Below is some code that I used while playing with formulas and
gadgets... hope it helps
function CalculateSum(Atext, Btext, form)
{
var A = parseFloat(Atext);
var B = parseFloat(Btext);
form.Answer.value = A + B;
}
function ClearForm(form)
{
form.input_A.value = "";
form.input_B.value = "";
form.Answer.value = "";
}
<FONT SIZE="+1">Your Add Box</FONT>
<FORM NAME="Calculator" METHOD="post">
<P><INPUT TYPE=TEXT NAME="input_A" SIZE=5> + <INPUT TYPE=TEXT
NAME="input_B" SIZE=5>
<P><INPUT TYPE=TEXT NAME="Answer" SIZE=12></P>
<P><INPUT TYPE="button" VALUE="Calc" name="AddButton"
onClick="CalculateSum(this.form.input_A.value,
this.form.input_B.value, this.form)"> <INPUT TYPE="button"
VALUE="Reset" name="ClearButton" onClick="ClearForm(this.form)"></P>
</FORM>
