[?]: TIA Timers programming

[papercuz]

This is my first time using a forum. If I am doing anything wrong, then please tell me so I can correct myself next time.
But anyways, I’m trying to do this mini practice which is
----------------------------------------------------------------------------------------------------------------------------------------------
2 lights (light 1 and light 2) are initially off, pressing a NO push button StartPB once, following sequence starts:

light 1 turns on for 4 seconds

light 2 turns on for 3 seconds

light 1 and light 2 flash/blink at 2Hz for 3 seconds

repeat above 1) & 3) continually

Pressing a NC stopPB once at any time of the sequence above, following extra sequence takes place once: a) finish the ongoing sequence until the step 3) above finished b) repeat the whole sequence step 1),2),3) above 2 times c) turn off all lights

This is what I have done. Sorry if I couldn’t show you the code in TIA. The service wouldn’t just open for me. I’m still in a learning process but I have no clue on how to do the step 3) and unsure if everything is correct?

What's the problem? Here everything is simple and there should be no problems.
