Problem displaying "reverse loop"

[CFdutch]

Hi I need some help with some reverse looping.

I receive a number as a variable. And from that point, I need to loop to 1. So if I receive 4, i need to ouput this

<select name="amount">
   <option value="4">4</option>
   <option value="3">3</option>
   <option value="2">2</option>
   <option value="1">1</option>
</select>

I tried with a loop, but I can't output a "reverse loop".
It should be pretty easy, but the problem is I'm working to a deadline and I'm sitting from 07:00 AM local(AMS) YESTERDAY :-s

So the best solution would be sleep, but the deadline is at the end of the day and I need some little things done like this one.

Please help me , thanks in advance and a meery x-mass and a happy 2005!!!!!

Here's an example copied straight from the CF Help files:

<cfloop index = "LoopCount" 
  from = "5" 
  to = "1" 
  step = "-1">
The loop index is <cfoutput>#LoopCount#</cfoutput>.<br>
</cfloop>
The output of this loop is as follows: 

The loop index is 5. 
The loop index is 4. 
The loop index is 3. 
The loop index is 2. 
The loop index is 1.

Notice the "From" and "To" attributes are backwards, and that the "Step" attribute is set to "-1", this makes the loop cound backwards.



Hope This Helps!

On that note even though documentation says "step" is optional, which it is because the default is 1. it is required in an instance like this.

<cfloop from = "4" to = "1" index = "i">
<cfoutput>#i#</cfoutput>
</cfloop>

will not work even with the from starting at 4 and the to is 1. Step IS required at this point to count backwords.

Its also a happy thing to use when you want to only count even or odd numbers. There is a lot you could do with it, not just even or odd numbers.

<cfloop from = "2" to = "10" index = "i" [b]step="2"[/b]>
<cfoutput>#i#</cfoutput>
</cfloop>

will produce 2 4 6 8 10

Thanks! That was just what I needed. I forgot the -1 step

Merry christmass to you all!
