How to force user to upload specific number of attachments?


Level 1

I have a form where users select checkboxes to attach a document.  I need to script that will compare the number of checkboxs selected with the number of attachments, and pop up an error message if these aren't the same.

Maybe something along the lines of;

var selectedCheckboxesCount = Subform1.resolveNodes('#field.[ui.oneOfChild.className == "checkButton" and $ == 1]').length;

var attachmentCount = == null ? 0 :;

if (selectedCheckboxesCount != attachmentCount)


app.alert("Something is missing")


Line 1 assumes all your checkboxes are in a subform called Subform1 and that they have the default value for true (which is 1), you may need to change these two things.
