I have this code in a form which calls the save function.

<TR><TD ALIGN="RIGHT">
<b>Valve Diameter in Millimetres </b>
</TD><TD>
<INPUT TYPE="text" NAME="VD" SIZE=7  onChange="save(stanForm.VD.value,
AInput, 'Valve Diameter')">
</TD></TR>

function save( field, vary, text ) {
     if( isNaN( field ) )
     {
        alert( text + " is not numeric" );
     }
     else
     {
         AInput = eval(field);  // this Works
         vary = eval(field);    // this does not workWorks
     }
}

Can anyone see what I am doing wrong?

Stan
