Pass data from a bind field error

[EdmondsM]

Hi all, I have a check box and a textfield binded together. If a user checks
the checkbox, the textfield gets todays date. I am getting the following error
message when I try to pass any values from either the checkbox or the textfield.

"Form entries incomplete or invalid."

Here is the code for the checkbox and the textfield.

<cfinput type="text" name="BriefSum_Date" bind="{(BriefSum.selected) ?
BriefSum_Date.text='#DateFormat(Now(), "mm/dd/yyyy")#':''}" width=75>
<cfinput type="checkbox" name="BriefSum" ID="BriefSum" label="Brief summary">

I am using the following code on the action page to collect the information

<cfoutput>
#form.BriefSum#
#form.BriefSum_Date#
</cfoutput>

Thanks in advance.
