What's wrong with this?

[Xv]

Below "code" is in the OnSuccess field of a form. Trying to display a diff screen based on the value of text field "Approved".

If(ThisItem.Approved="No", Navigate(Thank_you_screen,ScreenTransition.Fade), Navigate(Thank_you_screen_update,ScreenTransition.Fade))

Apps is not liking "ThisItem.Approved".  Tooltip says "Invalid use of ."

To start with - you have not provided any context to this formula. 

Where is this formula?  Is it in a Gallery or Form?  What is the Items property of the Gallery or Form?  

What kind of column is Approved in your DataSource?

All that info will assist greatly.

Right - I was adding the info as you replied.

So, the remaining question is - "what type of column is Approved?, but I can see that you have added a screenshot and some more information in your original post and it appears that you are using a form.

So, if that is the case, then your formula needs to be the following:

If(
   yourFormName.LastSubmit.Approved="No", 
      Navigate(Thank_you_screen,ScreenTransition.Fade), 
      Navigate(Thank_you_screen_update,ScreenTransition.Fade)
)

Thank you. Where can I find documentation on this?
I did specify that the field is type Text.

If it is text, then yes, that formula should work fine now.

You can learn more about EditForms from the documentation.  Or, you can watch my comprehensive video on EditForms (and how to go way outside of the box with forms).  It's a long one, but it will answer most every question you have on them.  And there is a table of contents in the description of the video, so you can jump to certain reference points as needed.

Thanks again - I will check these out.
