I wear a lot of hats...

You will need to use the RND function, which returns a 0 to 1 value (decimals).  So you will need to do some math with that to normalize it into the range of values you want.  Take a look at the code at this link and let us know if you still have questions.

Assuming it can be anything in the range 0000-9999...


TheCode = Right("000" & Int(Rnd * 10000), 4)

I found this one;

<script type="text/vbscript">

Dim max,min
max=100
min=1
Randomize
document.write(Int((max-min+1)*Rnd+min))

</script>

If I need 4 numbers I could use:

<script type="text/vbscript">

Dim max,min
max=9999
min=1000
Randomize
document.write(Int((max-min+1)*Rnd+min))

</script>

That way it needs to have 4 digits, now .. how do I call this function to set the value of the hidden field to the results of the above ?

Okay, in this case I think you want something like this, but I welcome other experts insight.  First, create a function to generate the 4 digit number:

<% function randCode
  dim max,min
  max=9999
  min=1000
  randomize
  randCode=(Int((max-min+1)*Rnd+min))
end function
%>

you can reference it like this:

<%=randCode%>
