It never occurred to me that I could combine those 3 scripts. I shall experiment.
I never knew you could limit the number of digits inputted or exclude letters. I shall google a tutorial on that.
Don't I need to keep the Grand Total in an input box so the total gets sent with the form data submission? I found that data in divs doesn't get sent...perhaps because I didn't name them, only id'd them. Hmm. I'll have to experiment with adding ids AND names to divs and see if the data gets sent. My newest version has names added to the input values and it submits the values now.
As for displaying a running total, that sounds awesome. I'm intrigued that it doesn't involve a function. So I'm thinking it is a variable that is the sum and a variable that is an innerHTML. I shall experiment with that to test it out.
On a side note, can the data sent by a form submitted by mailto contain CSS so that when the data shows up in the email it doesn't look like ...crap?
Thank you for your guidance sunfighter
