A problem of controlling duration of a loop

Dear Sir or Madam,

I want to set the duration of the loop (named trials) not more than 8 seconds. If the duration of the total trials in Condition of the loop, it should be end and entry to the ‘bye’ routine.

I would appreciate it if you could help me with this.
