Ok i have an edit page..
its like this.. it reads a Y/N value from a database.. and poplates the checkbox as such..
next to it is a file upload.. which i want to work only if the user clicks it..

so basically how do i check whether anything is in the input file tage.. so i can upload a file if it doesnt exist..

<cfparam name="yourQueryName.yourBooleanValue" default="false" type="boolean">

<input type="checkbox" onClick="document.getElementById('myFile').disabled = (document.getElementById('myFile').disabled == false) ? true : false;" value="true"<cfif NOT yourQueryName.yourBooleanValue> checked</cfif>>
<input name="myFile" id="myFile" type="file"<cfif NOT yourQueryName.yourBooleanValue> disabled="true"</cfif>>

<cfparam name="yourQueryName.yourBooleanValue" default="false" type="boolean"> should really be a value from your database, a boolean value, i.e. 0/1 yes/no, true/false

why u wanna make the file upload dependent on the checkbox ?
u cld just chk if the user has selected a file for upload or not - if he has upload it - else dont

with having checkbox - u'll see that user may select the file & if he unchecks the checkbox - the file will still get uploaded - leaving the element of "confusion".
u might go ahead & avoid all this & then later on u'll realise that "disabled" dosent work in "netscape" [i know not many users use it]. but u have a loop hole left in there for netscape users!

rest depends how u wanna set things for ur site.

Or you should explain what you are after in a different way, I think you threw everyone off with you mentioning the checkbox.
