Issue publishing to gallery getting No valid fields selected

[infiniteLoop]

I am trying to publish a workflow which is a app to the gallery which takes

1)Input from a folder -to make it dynamic I have used  text input where user is prompted to enter the path 

    and have used Dynamic input tool for generating a Full path followed by select tool

2)Generated report 

3)notifies to the user mail id

It runs perfect while running through Designer.

While Publishing it gives error on select tool placed after Dynamic input tool.

Attached is the error

Please if someone can assist in this

My guess is that you need to look at your input and ensure the server can see it. An easy way to test is to just put the first tools (with dynamic input) in a workflow and publish it and run it. If that works then you can troubleshoot your select tool.

Dyamic Input tool works good only issue is with the select tool placed after it.
