I had to reformat your procedure to be able to match the 
brackets more easily:

to test
setseconds 0
t2, setpos [217 -8]
t1, setpos [-245 -4]
t2, clickon

forever [
 t1, towards "t2
 
 resett
 t1, clickon
 t2, clickon
 
 setseconds timer / 10
 if seconds = 100 [
  question [You won Next stage? yes/no]
 
  if answer = "yes [page2]
  if answer = "no [stopall] 
  
  if touching? "t1 "t2 [
   announce se timer / 10 "seconds
   stopall
  ]
  
 ]
]

end


Then I saw that you are resetting the timer forever, 
and you are clicking on the turtles forever. 

I moved those instructions outside the forever:

to test
setseconds 0
t2, setpos [217 -8]
t1, setpos [-245 -4]

resett
t1, clickon
t2, clickon

forever [
 t1, towards "t2
 
 setseconds timer / 10
 if seconds = 100 [
  question [You won Next stage? yes/no]
 
  if answer = "yes [page2]
  if answer = "no [stopall] 
  
  if touching? "t1 "t2 [
   announce se timer / 10 "seconds
   stopall
  ]
  
 ]
]
end


This part is also suspicious:

...
  if answer = "yes [page2]
  if answer = "no [stopall] 
  
  if touching? "t1 "t2 [
   announce se timer / 10 "seconds
   stopall
  ]
...

there are two possible outcomes here:

1. the answer is yes and we go to page2, do you still want to check collitions 
afterwards?

2. the answer is no and everything stops, in that case the program never 
reaches "if touching".
