Then I get this error:
It says unknown parameter.
Then I get this error:

Thank you for the tip, I did as you told me and it worked properly, I also finished my circuit but there's last error. Please check what's causing this. Thank you!
Sorry just a noob...
"...I did as you told me and it worked properly..."
No you didn't and no it doesn't.

which tells you to:
where link number 3 says:
and the introduction to that document says:
and:
@andyfierman Yes, directing me to the document. I did read it but still doesn't quite understand as I am really new to this one... So your help would really be appreciated. I hope you could tell me which part of the connection is the mistake.
" I did read it "
What: all of
https://docs.easyeda.com/en/Simulation/Headings/index.html
including the section that describes where to find simulatable components unlike those such as U1 and, I suspect, the pots, that you have placed in your schematic?
If you have made your project public so that others can study it and maybe offer suggestions then please post the url to it here.
@andyfierman I did use spice model in my 555 timer. And now I changed the pots with the ones from the spice. It says now that the cpu cannot handle the circuit.
"If you have made your project public so that others can study it and maybe offer suggestions then please post the url to it here."
Since you have failed to post the url to your public project or given a reason why you have not done so, I have taken the liberty of doing it for you:
https://easyeda.com/qjygsantos/final
and documenting the changes that you need to make to make it run.
Now, for the final time of asking: read all of - and play with all of the examples in - the Simulation Tutorial.
Then go back to your simulation and first do:
File > Export Netlist > LTSpice for this Sheet...
Download and study the netlist.
Then:
Now do:
File > Export Netlist > LTSpice for this Sheet...
Download and study the new netlist.
Compare it with the original netlist.
Your simulation will now run.
Note that placing the interactive LEDs from the Commonly Used Library (was EELib) inhibits WaveForm display. You will learn more about how your circuit is operating if you delete these LEDs, replace them with DLEDR, DLEDG, DLEDY or DLEDO Spice Symbols from the Spice Symbol Library and then place Voltage Probes around your sim to see in the time domain what your circuit is doing.
Note also that the prefix and pin renumbering of the LM358-N is so that it matches the pinout in your original design and so should still update the PCB OK though you may need to do Rests Component ID in both the schematic and the PCB first.
So, I'm only giving you 3 out of 10 for your Final Project because you do not pay enough attention to information that you are given.
In the schematic that you show you appear to have edited the symbol for a current source and turned it into the symbol for a buzzer or a loudspeaker. It is not clear why you have done this because the simplest way to represent a buzzer or loudspeaker - without going into some very complex simulation techniques to represent loudspeaker back emfs and microphonic effects - is as a resistor such as in RSPKR in this simulation:
https://easyeda.com/editor#mode=sim,id=7975219d29684700820e33bf631e060d
You simulation will not run as expected if at all because you have:
Note also that you also appear to have left pin 4 of U1 pulled low so U1 is permanently in the reset condition.
