component variables to GetUrl Post

I have created a form using input text fields, named each one in the variable box on the properties panel.  I added a button GetUrl using the Post or Get this works fine and I can access the data in CF.

I want to add a Date Field component to the stage and pass the selected date along with the other text field info.  At present when I click the button the following text is outputted:-

"/index.cfm?width=undefined&height=undefined&focusManager=%5Flevel0%2EfocusManager&tabChildren=true&tabEnabled=false&firstname=jill&%5FchildCounter=1&focus%5Fmc=%5Flevel0%2EdepthChild0&lastname=juuu"

Can anyone help me in posting the date field component information (also help passing the info for check boxes, radio buttons etc as i have the same problem with them).  I am sure there is a simple explanation, but at the moment I cannot find it myself.

I would obviously offer more points, but at present do not have a credit card and am in the UK and  my card type is not accepted and so cannot purchase any additional points.  Thanks......

How is the button script?
juztynCommented:
You can use the command:

 loadVariables ("url" ,level/"target"[, variables])

except you will omit the variables argument and instead craft the url that is sent yourself. This allows you to specify exactly which variables you want sent, including variables not generally available when you use the default variables argument:

loadVariables("http://yourserver.net/index.cfm?width=" + width + "&date=" + date + "&anotherVariable=" + anotherVariable, _root);

Hope this helps.
