Dreamweaver CS6 locking up

Question

I am using Dreamweaver CS6, Version 12 with WIndows 8.1
Creating a dynamic web site following David Powers tutorial at Building your first dynamic website – Part 2: Developing the back end | Adobe Developer Connection
(Which gives you an idea of my level expertise)
I am modifying the forms to suit my needs but otherwise no changes to David's instructions
I am the stage where I have built the add, manage, update and delete forms and added the various Server Behaviours. Everything works as it should on testing.
Problem
Next stage is to create edit and delete links.
I select Edit from the page that lists all records (manage_posts in tutorial)
Select URL from Select File box
Click on Parameters from File box
Enter be_index (the primary key of the records) in the Name box
Click on Value lightning bolt
Dreamweaver totally locks up. Need to use Task Manager to close it down and regain control.
I have tried re-installing Dreamweaver, and deleting cache as suggested elsewhere on this site, to no avail. Database appears OK when examined with phpMyAdmin.
I have tried hand coding using the line
        <td><a href="update_records.php?be_index=<?php echo $row_rs_benefactions['be_index']; ?>">Edit</a></td>
but it doesn't do what it is supposed to do i.e. create line of code that points too each record's primary key.
I would appreciate any help to overcome this solid barrier.
Many thanks

Maybe this should be a new post but it is is closely linked to my first post in this thread so I am adding it here.
The original (edited down) question was

Snip.
Next stage (following tutorial) is to create edit and delete links. I select EDIT from the page that lists all records (manage_posts in tutorial)
Select URL from Select File box, click on Parameters from File box, enter the primary key of the records in the Name box.
Click on Value lightning bolt. Dreamweaver totally locks up. Need to use Task Manager to close it down and regain control.
What it should do is insert a line in the pages code -
<td><a href="update_benefactions_record.php?be_index=<?php echo $row_rsBenefactions[`be_index`];?>">EDIT</a></td>
Since trying to insert this code via the DW facility locks everything up, I tried entering the line by hand.
According to the tutorial what this should do is select the appropriate record from the record listing table and show the entire record in the updating page.
i.e If I select the 3rd record, using Live view I should see the code
<td><a href="update_benefactions_record.php?be_index=3">EDIT</a><</td>
Unfortunately I don't, so I am completely stalled.
