WorldViz User Forum - what does this error code mean?

Heya im getting this error, im trying to make it so when the left mouse button is pressed an event occurs,

but i Keep getting the following error:

UnboundLocalError: local variable 'info' referenced before assignment

any thoughts? the code is below:

Code:

import viz



import vizinfo

viz.go()



ground = viz.add('tut_ground.wrl')

avatar = viz.add('vcc_male.cfg')

female = viz.add('vcc_female.cfg')



viz.translate(viz.HEAD_POS,0,20,-30)

viz.lookat(0,0,0)

viz.mouse(viz.OFF)

viz.clearcolor(0.5,0.5,1)





#Add the vizinfo object with a message.

infoObject = vizinfo.add('Give me feedback!')

infoObject.visible(0)

#Give it a title.

infoObject.title('Vizinfo box')

#Add GUI elements with labels.

button = infoObject.add(viz.BUTTON, 'Push me')

slider = infoObject.add(viz.SLIDER, 'Slide me')

check = infoObject.add(viz.CHECKBOX, 'Check me')

#Adjust the parameters of one of the GUI elements.

slider.vertical() 



def mouse(button): 

                if button == viz.MOUSEBUTTON_LEFT:

                        info = viz.pick(1)

                        if info.valid and info.object == ground:

                                walk = vizact.walkTo([info.point[0],0,info.point[2]])

                                avatar.runAction(walk)

                        

                if info.valid and info.object == female:

                                infoObject.visible(1)

        

viz.callback(viz.MOUSEDOWN_EVENT,mouse)
