I want to do a sort of timer countdown

Else after 6 (while runnning the sound) it opens the door
This is my program, (what I have done until now)
OR, it is impossible?

Take a look at loops and testing the button each time through the loop.

Currently your program doesn't give enough time to press the button before it starts playing the tones. Franklin is correct in that you will need a loop. However the BASIC Stamp Microcontroller is single tasking and can only do one thing at a time, so in your loop you have to be sure you're not doing anything that might cause the button press to be missed. Currently the tone is being played for 1/4 of a second which may also cause the button press to be missed. You may want to reduce the amount of time it plays for and play multiple short bursts within the loop while testing the button. The number of iterations of the loop will have to be determined imperically or calculated by the time of the instructions if you want to get as cloe to 6 seconds as possible.
