Variable problems in HTML / Vbscript

[craigpollard]

Hello
I have a form where the user chooses to "check" one variable from a list of many.
I then want to take that variable and multiply it buy a number. Eg I want 3 wigits...
It will work if I place the "multiply" variable in another table from the "checkbox" variable, but when I put them next to eachother in the same table the "multiply" variable is not recognised by vbscript????
Does anyone know why?

<TD>My Variables<INPUT TYPE="checkbox" NAME="variablename0" Value="250">
<SELECT NAME="multplyvar0">
<OPTION value = 1>1</option>
<OPTION value = 2>2</option>
</SELECT>
</TD>

Then in vbscript

If form.variablename0.Checked Then
total = (total + cint(form.elements(0).value)) * multplyvar0.value
End If

Cheers
