It sounds like your values are being recognized as strings vs. expressions.
if they are strings the + sign will concatenate them. if they are
expressions then + will add the two together. cut and paste the following
scripts into a page and run them:
<script language="JavaScript">
fred="5"
george="6"
total=fred+george
alert(total)
</script>
<script language="JavaScript">
fred=5
george=6
total=fred+george
alert(total)
</script>
the first script returns 56 because 5 and 6 are recognized as strings. the
second will return 11 because they are recognized as expressions. i hope
this helps

+ is for concatenating strings (spelling?)
++ will add them up i think.

Subject: OT: javascript add problem
Sorry about the OT question, but am stumped as to why this won't work.
Trying
to use JavaScript to add the numbers in form fields together, instead of
adding them, it is appending them to each other. Here is my code:
<script language="JavaScript">
function AddToBasket()
{
OrderBooks.TotalQty.value = 0
OrderBooks.TotalQty.value = eval(OrderBooks.SW.value +
OrderBooks.SP.value)
}
</script>
It is taking the value of OrderBooks.SP.value and apending it to
OrderBooks.SW.value instead of adding them. For example,
OrderBooks.SW.value
= 3 and OrderBooks.SP.value = 5, I am getting 35 instead of 8. Have tried
it
without the eval() in there and have set each form value equal to a
javascript
variable also with no change in results.
