I'm using three textboxes. Two of which are related by using the <cf_TwoSelectsRelated>. I need to add another textbox which is based on the result of the previous used box. For example textbox #1 called Release is linked with textbox #2 by using <cf_TwoSelectsRelated>. Now I want to link textbox #3 results based on the selection of textbox #1. I know I need to use the onChange function. but i'm not sure how. I'm fairly new using ColdFusion and would like to get some help. Look forward to hear some suggestions.

your textboxes :
<input type=text name=release onchange="javascript:toto()">
<input type=text name=box2>
<input type=text name=box3>
now :
- the javascript function called when the user changes the value of the 1st textbox is toto() (you have to define it, usually in the header, between tags <script> and </script>
- in this function, to retrieve the value entered in the 1st textbox : document.the_name_of_the_form.release.value (something like : if (document.the_name_of_the_form.release.value < 0) )
- and to set the value of the 3rd textbox : document.the_name_of_the_form.box3.value (something like : document.the_name_of_the_form.box3.value=2)
for more i need more info from you

Now this is basically the current way i've got two cf statements connected to automatically populate the second drop down box. I refer to another file called "TaskTwoSelectsRelated" which based on the release populates the type of groups that exist for that particular release.
What i want to do is based on the release be able to add another drop down box which would display "activity." So basically the boxes are related based on the release.
Further on i will be adding another list box "details" which will display results based on the activity. I hope this helps.
I'm farily new to this site myself...Is there a way I may be able to attach a file? I would also like to show what I've done with the "TaskTwoSelectsRelated."
