Finding totals and restricting format...

[WhiteTiger]

How can I restrict text boxes to be numbers only format?

And how, when the focus is acheived or lost, can I get 1 'total' textbox to calculate values?

I'm looking to do an excel type thing, but its mainly for entering dollar amounts for employee reimbursement if they use their car, or perhaps, for us to bill a company Regards,

Ok, I got it to check, but how would I change the text to go blank if it 'errors'?

Also, is there a way to check on keypress? Regards,
