Condition to Notify if it already exists - error: Invalid argument type

I have a form: EditForm1

The main question is for the end user to supply a ProjectID

 

If that ProjectID already exists in the entity, Id like the end user to receive a warning that it already exists.

 

This is what I have so far, however I'm getting an error on the first equal sign that says "Invalid argument type":

 

 

If(!IsBlank(LookUp(ProjEmergencies, ProjectID = ComboBox3.SelectedItems.Result))=false, Notify("That Project already exists",Warning), SubmitForm(EditForm1);Navigate(BrowseScreen1,ScreenTransition.Fade))

 

 

The data is being put into an entity on the common data service.

 

what am I doing wrong?

I think this may have something to do with the CDS columns need to be in a certain state, some setting in PowerApps I think?

Hi @TesDA ,

Try

If(
   IsBlank(
      LookUp(
         ProjEmergencies,
         ProjectID = ComboBox3.SelectedItems.Result
      )
   ),
   SubmitForm(EditForm1);
   Navigate(BrowseScreen1,ScreenTransition.Fade),
   Notify("That Project already exists",Warning)
)

I also got rid of the Not argument which is not delegable.

That doesn't appear to be the case. I have marked the solution from another user I implemented first that worked.
