hello everyone.. im having an issue setting up a cascade on a relationship between two tables.. when i leave the delete action to 'no action' it doesnt give me any errors but ofcourse i want to utilize this method.

Im getting this error when i try to set the delete action to null.

'csUsers' table saved successfully
'csPhoneNumbers_Requests' table
- Unable to create relationship 'FK_csPhoneNumbers_Requests_csUsers1'.
Introducing FOREIGN KEY constraint 'FK_csPhoneNumbers_Requests_csUsers1' on table 'csPhoneNumbers_Requests' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
Could not create constraint. See previous errors.

CREATE TABLE [dbo].[csPhoneNumbers_Requests](
	[ID] [uniqueidentifier] NOT NULL,
	[OwnersUserID] [uniqueidentifier] NULL,
	[OwnersEmail] [varchar](128) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
	[PhoneNumberID] [uniqueidentifier] NULL,
	[PhoneNumber] [char](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
	[RequestingUserID] [uniqueidentifier] NULL,
	[RequestingEmail] [varchar](128) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
	[RequestDate] [datetime] NOT NULL,
	[RequestStatus] [tinyint] NOT NULL,
	[DeleteDate] [datetime] NULL,
 CONSTRAINT [PK_csPhoneNumbers_Requests_1] PRIMARY KEY CLUSTERED 
(
	[ID] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

GO
SET ANSI_PADDING OFF
GO
ALTER TABLE [dbo].[csPhoneNumbers_Requests]  WITH CHECK ADD  CONSTRAINT [FK_csPhoneNumbers_Requests_csPhoneNumbers] FOREIGN KEY([PhoneNumberID])
REFERENCES [dbo].[csPhoneNumbers] ([ID])
ON DELETE SET NULL
GO
ALTER TABLE [dbo].[csPhoneNumbers_Requests] CHECK CONSTRAINT [FK_csPhoneNumbers_Requests_csPhoneNumbers]
GO
ALTER TABLE [dbo].[csPhoneNumbers_Requests]  WITH CHECK ADD  CONSTRAINT [FK_csPhoneNumbers_Requests_csUsers] FOREIGN KEY([OwnersUserID])
REFERENCES [dbo].[csUsers] ([ID])
ON DELETE SET NULL
GO
ALTER TABLE [dbo].[csPhoneNumbers_Requests] CHECK CONSTRAINT [FK_csPhoneNumbers_Requests_csUsers]
