# 'Can't find element' message when using square brackets

If you're adding square brackets \[] around your ID attribute to help with spacing, you may encounter this error message when you're running the 'Generate PDF Creator' action:

### <mark style="background-color:purple;">Sorry, we couldn't find this element: "\[target-element]"</mark>

This typically occurs if you're also using the [Classify plugin](/pdf-creator/implementing-key-features/sending-pdfs-via-email.md). The Classify plugin unfortunately causes an issue with how ID attributes are interpreted by PDF Creator, which means you can’t use the \[] around an ID attribute.

## **Solution**

If you add a \* before and after the ID attribute of the repeating group you are PDF-ing and you will get the same affect as the  's. For example, if your repeating group has the ID attribute:

### <mark style="background-color:purple;">my-repeating-group</mark>

You can add a \* before and after to get:

### <mark style="background-color:purple;">\*my-repeating-group\*</mark>

There is no conflict with the Classify plugin when you use this command.
