html - input boxes and resetting

[BearX00]

Im creatinga web page that has a table with form input.. the form also does automatic totaling of the rows onchange. so for each input which is a text i had to create a variable in the inputs definition called oldvalue. when the form is reset, oldvalue does not get reset for all the elements in the table. I suppose i could manually reset all of the oldvalues but there are 130 of them and that would just be extra code. if there is another easy way to reset oldvalue to 0 when the reset button is pressed id appreciate it if someone could enlighten me. thanks
