Button to Notify if a field is matched in a sharepoint list

I am using PowerApps connected to a Sharepoint List "Contacts", with a field called Full Name.

I have a form which is opened in NEW mode to accept a new contact. I concatenate (First Name, " ",Last Name) in a label called CheckFullName, and have a button called CHECK which does the following:

If(IsBlank(LookUp(Contacts.'Full Name' = Checkfullname)),Notify("Name exists",NotificationType.Warning))

This shows errors:  Incompatible Types for Comparison..Button3.Onselect

                               

Full Name is a String; I tried using CheckFullname.Text but still get incompatible types.  Also do not understand Invalid no. of arguments.

I removed the NOTIFY command and replaced with changing a Text box (Label) message to visible, but this didn't work - so then just tried to make the button change the label to visible, but it still didn't work.  Can you not change the properties in a form in NEW mode?  Sorry if this is more than one question!!

Sorry I am moving at a tangent; the Gallery is basically my way to allow the user to lookup if the name already exists: the ITEM property of the gallery is : Filter(Contacts, StartsWith('Full Name', FName.Text)), where Fname is the textinput box for First Name (which seems to be enough to view matching records).  If the user should want to edit the record (missing or incorrect data), I want to click the select arrow in the gallery to move to a new screen called CLIENTDETAILS with a form called EDITFORM1.  I use this code on the arrow: ViewForm(EditForm1);Navigate(ClientDetails,ScreenTransition.CoverRight).  The datasource of EDITFORM1 is Contacts, and the Item property is BrowseGallery1.Selected

It shows the first record, not the selected one.

I want to add another button that allows the user to create a new record if there is no match.

Thanks for your patience.

@jms345 ,

Firstly, the record in the form should be the one selected if what you posted is correct - you can try this - Gallery OnSelect

Set(
   gblID,
   ThisItem.ID
);
ViewForm(EditForm1);
Navigate(
   ClientDetails,
   ScreenTransition.CoverRight
)

The Item of the Form

LookUp(
   Contacts,
   ID = gblID
)

For a new record, all you need is

NewForm(EditForm1);
Navigate(
   ClientDetails,
   ScreenTransition.CoverRight
)

 

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.
