Is this positive, negative or faulty!!

I took a clear blue pregnancy test this morning. For a positive result, one vertical line appears, in the positive window a horizontal line came up instead? Has anyone had this before. Thanks :)

I would go and get a first response test instead just to be sure on the result. I took a few clear blue digitals and got about 3 error signs in mine when I was ttc so gave up on them completely
