So it should be the following:
For every docx file in the "files in directory" collection Open all files by "pages app" but I can't see both "Open all files inside folder" function and my results are just like that:
In the Open Action, you need to enter the Variable token for the Variable used in the For each Action.
BTW, in the future, please drag/drop or copy/paste all images you need directly into the forum post. No need to use a third party image service. I have replaced your droplr link with the actual image.
In the KM Editor app, you can just select one or more Actions, and then goto menu Edit > Copy as > Copy as Image. Then paste into the forum.
This little chore is not hard to accomplish, but there are some niggly details that take getting used to – such as the difference between a text field and a variable field.
