how to force type cast ?

[dan baker]

a simple question... I have a case where I' dlike to add values as
numbers and they seem to get added as a string concatination. how do I
force the + to add the values as numbers?

this is in an <INPUT onchange="OrderForm.TotalCharge.value=this.value
+ 1;" >

a related question is that I have some other calculations to do in
addition to this one-liner, so I am assuming I should write a little
<SCRIPT> function and just make the onchange="MyReCalc();"

thanks,

thanks... I figured that the INPUT was treating things as text
strings, but had not found the parseInt() and parseFloat() functions
before.
