Q692 How can I pass the data entered in one form to another form in the same page?

Something like:

document.formName2.elementName.value = document.formName1.elementName.value

Perhaps as part of an onClick event handler:

<FORM NAME="formName1">
<INPUT TYPE="TEXT" NAME="elementName">
</FORM>

<FORM NAME="formName2">
<INPUT TYPE="TEXT" NAME="elementName">
<INPUT TYPE="BUTTON" VALUE="Click Me" onClick="document.formName2.elementName.value = document.formName1.elementName.value">
</FORM>
