How to uncheck a checkbox on a particular condition in classic asp?

I have a check box which is by default checked and based on the value from the database it has to be unchecked. For checking the check box the keyword is checked="checked" what is the keyword for unchecking. Please reply on this.

Thanks & Regards,

Try checked="" or removing checked entirely.

Actually this is the condition

<td width="70%"><input type="checkbox" name="chkparticipate" checked="checked" value="Y" <%if confirmation=false then%> checked="" <%end if%> onclick="checkGropPartipation1()">


so its not working. Can you suggest me how to debug the classic asp page.
