Nokia 7373 Mobile Phone Camera problem

[HappyFace]

My daughter has the above phone and when she goes to take a photo it says on screen 'camera on standby'. The picture has not been taken. Any suggestions as to what is causing this and how to resolve it?

To have the still image function, press the camera key in the standby

scroll left or right.
To take an image in landscape

To take an image, select Capture, or press the camera key. The phone
saves the images on the memory card.
Select Options to set Night mode on if the lighting is dim, Self-timer on

a sequence; with other size settings five images are taken.
