Error Inserting Row In Table Where There Is Multiple Foreign Key.

Hi guys,
I have created 3 tables namely Static, Dynamic and Demo...
Static has colums FormID(uniqueidentifier, PrimaryKey) and FormName(Nvarchar(50)).
Dynamic has colums formID(uniqueidentifier,PrimaryKey) and FormName(Nvarchar(50)).
Demo has 4 colums namely ValueID(uniqueidentifier, Primary Key), formID(uniqueidentifier, foreign key), Name(nvarchar(50)), Value(nvarchar(50).

Now the formID coloum in Demo table i have set as foreign key to both the dynamic table as well as static table on the formID colum in both table.

Now first i insert a row in the dynamic table then take the uniqueidentifier which is generated automatically and try
to insert in the Demo table in formID colum as that colum is FK to dynamic and static but when i try to insert a row it show that its violating the FOREIGN KEY CONSTRAINT

the exact error is

Msg 547, Level 16, State 0, Line 1

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Demo_Dynamic1". The conflict occurred in database "huzefaJTest", table "dbo.Dynamic", column 'formid'.

The statement has been terminated.

please if anyone know do reply.....
