Still didn't work.  I've included the relevant code this time.
When I click on the button to add, this.form is sent to the function
addition, which takes two fields with numbers.  I add them, but it
concatenates them.  I took your suggestion and made it (1* # + #) as shown
below, but it still doesn't work.

Any more suggestions out there???  Thanks in advance,

function addition(form) {

function equals(form) {
  form.currentnum.value = eval(form.hiddennum.value)
// end hiding contents from old browsers  -->
<INPUT TYPE="BUTTON" VALUE=" + " onClick="addition(this.form)">
