Hi Marc,
You don't have to know the actual coordinates, except for special
occasions (client-side image maps).
So, add a name to the graphic input on the form:
<input type="image" name="deleteYes" ...>
You're just checking to see whether those *variables* are present, not
what their values are. So, you'll end up with two form variables:
form.deleteYes.x
form.deleteYes.y
where
form.deleteYes.x=10 // or some other integer (not important)
form.deleteYes.y=8 // or some other integer (not important)
Just check for variable presence, though, since it won't exist without
a click:
<cfscript>
<cfif isdefined('form.deleteYes.x')>
<!--- your delete code goes here --->
</cfif>
</cfscript>
That should work "out of the box."
Let me know if you have questions.
Jamie
