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?

If(CountRows(Filter(ProjEmergencies,ProjectID=ComboBox3.Selected.Result )) > 0,
Notify("That Project already exists",Warning), SubmitForm(EditForm1);Navigate(BrowseScreen1,ScreenTransition.Fade))

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.
