Here's a copy of your 'Form page' document back, with:
1. a custom document property named 'CheckNo'; and
2. the INCLUDETEXT field with a:
(a) FILENAME field being used to generate a relative path to the Test1.docx file. Simply omitting the path is not reliable;
(b) bookmark reference to your Test1.docx file's Test bookmarks; and
(c) DOCPROPERTY field referencing the 'CheckNo' custom document property to vary the bookmark number. Currently it refers to Test bookmark #1.

Simply save the file to the same folder as your Test1.docx file and everything should work fine. If you change the 'CheckNo' custom document property value from 1 to 2 and update the INCLUDETEXT field (e.g. via Alt-A, F9), the document content will change to reflect whatever is in the Test2 bookmark. If you edit the content of either bookmark and update the INCLUDETEXT field the reference will also update.

To change the 'CheckNo' custom document property value, go to File>Properties>Advanced properties>Custom.
