Hi there.  I'm not doing anything really important, but I can't figure out why this code doesn't work.  Can someone point me in the right direction.

<code>
<HTML>
<HEAD>
<TITLE> My First Attempt at VB Script!</TITLE>

<SCRIPT LANGUAGE="VBSCRIPT" TYPE="text/vbs">

<!-- Instruct non-IE browsers to skip over scripts

    Sub MYBUTTON_OnClick
     MsgBox "Over the hills and through the woods, to grandmothers house we go!"
    End Sub

    Sub MYBUTTON2_OnClick
     DIM X
     X = INPUTBOX("Enter Your Name:")
         if X = "" then
          Exit Sub
         end if
     MsgBox "Your Name is: " & X
    End Sub

    Sub CALC_OnClick
     msgbox ((document.myform.FSTNUM.VALUE) + (document.myform.SECNUM.VALUE))
    end sub
-->
</SCRIPT>
</HEAD>

<BODY BGCOLOR = 'beige'>

<FORM NAME = "myForm">
    <INPUT TYPE = "BUTTON" NAME = "MYBUTTON" VALUE = "WOO - HOO">
    <INPUT TYPE = "BUTTON" NAME = "MYBUTTON2" VALUE = "NAME SCRIPT">
    <INPUT TYPE = "Text" NAME = "FSTNUM" VALUE = 0 SIZE = 4>
    <INPUT TYPE = "Text" NAME = "SECNUM" VALUE = 0 SIZE = 4>
    <INPUT TYPE = "BUTTON" NAME = "CALC" VALUE = "CALCULATE">
</FORM>

</BODY>
</HTML>
</code>

in the Calc_OnClick, the message box returns the values of the text boxes concatenated.  If I try multiplying, it works fine.

Thanks for any help.

  Sub CALC_OnClick
    msgbox (eval(document.myform.FSTNUM.VALUE) + eval(document.myform.SECNUM.VALUE))
   end sub

without the eval() , the input values are treated as text, so you are concatinating two strings together.

actually, you may want to use CInt instead of eval:


   msgbox (CInt(document.myform.FSTNUM.VALUE) + CInt(document.myform.SECNUM.VALUE))
