This problem is widespread and so I'd like you to just take a moment while I explain something.

It's SPELLED L-O-S-E not L-O-O-S-E.

lose
v., lost (lôst, lŏst) los•ing, los•es.

To be unsuccessful in retaining possession of; mislay: He's always losing his car keys.

To be deprived of (something one has had): lost her art collection in the fire; lost her job.
To be left alone or desolate because of the death of: lost his wife.
To be unable to keep alive: a doctor who has lost very few patients.
To be unable to keep control or allegiance of: lost his temper at the meeting; is losing supporters by changing his mind.
To fail to win; fail in: lost the game; lost the court case.
To fail to use or take advantage of: Don't lose a chance to improve your position.
To fail to hear, see, or understand: We lost the plane in the fog. I lost her when she started speaking about thermodynamics.

Loose is something completely different.

Thank-you.
