empty or null default value for a numeric variable

[pitz77]

Hi,

I would like to default a numeric variable to empty. The situation is that I've got a page that takes FORM/URL scope variables from the previous page and from a post back of itself. Here's some code:

<cfparam name="fooPostBackVar" type="numeric" default=??>
<cfparam name="fooLocalVar" type="numeric" default=#fooPostBack#>

<input type="text" value="#fooLocalVar#">


The first time the user comes to the page, I'd like fooLocalVar to be null yet still retain the datatype in case of a postback.

The question: what to I put in place of default=??.

i think you can actually remove it altogether, default= is an optional attribute.

Nope. I did that and I get this error because I use "fooPostBackVar" to define "fooLocalVar".


The required parameter fooPostBackVar was not provided.
This page uses the CFPARAM tag to declare the parameter mon_CLINqty as required for this template. The parameter is not available.Please verify that you have passed or initialized the parameter correctly. If you wish to set a default value for the parameter you should use the DEFAULT attribute of the CFPARAM tag.

I'd say:

<cfparam name="fooPostBackVar" type="numeric" default="">
<cfparam name="fooLocalVar" type="numeric" default="#fooPostBack#">

<input type="text" value="#fooLocalVar#">

I'm sure you tried something like that.. If you did or that doesn't work or whatever...

<cfparam name="fooPostBackVar" default="">
<cfparam name="fooLocalVar" type="numeric" default="#fooPostBack#">

<input type="text" value="#fooLocalVar#">

Thanks, but neither of those will work for me. The first and second both set numerics to empty strings, which will certainly fail.

I still have yet to come up with a solution.

Any ideas are still welcome...

Can you cfparam the value to 0 and if its 0 not do anything?
