All you appear to be missing is a closing angle bracket at the end of your cfform tag.
I missed it when I typed it in my original question
The > bracket is in my code.
I justed checked.
It should read ~ "detail.cfm">
The list works when I excute the page.
How do I pass the value after I have selected it on the page?
cfdump your form scope. You should see it.
got it thanks
