i am nab at scripting, you can try this 
item_pickup_trig waittill("trigger");  But what i was really wondering is that, in your map in radiant is it misc_model or script_model, it should be script_model as far as i know. That's what can i suggest right now, hope you solve it.

  Give more information, and any Screenshot if it's possible.

np man, just keep it always on admin mode, but still i dont know what actually does cause this error  because it always happens to me, even if i would format the entire laptop, but anyway as long as the admin mode fixes it we gonna be fine i guess 

This actually worked! I'm so happy because I used to have a previous desktop that would always refuse to get past the error. But now since I built this current pc and tried to see if it'd allow it better, with the admin mode, it did unlike the previous prebuilt computer I had. I find that odd and wonder. Oh well. Other than that it works on my current pc! Thank you so much! 

Hello, I am faced with an error that I can not solve!

I am not sure but could it be you are trying to add new pap camo's and it didn't work?

Follow these 3 things:
1. Add the images to your mod.
2. In the modbuilder the images.
3. For sure also add the images to your raw/images folder as backup.

When I click, "Continue," I noticed it doesn't allow me to continue to make the map.

What Klevi said you can try to run the application in Admin mode. 

Hi, I can not understand why I have it all wrong

You can simply ignore that list because it also includes campain (x)animations.

Ahhahahaha haha this shit stupid error, it happens to me always, right click on launcher and compability, run as an admin. Idk if it will work for you but with me works always. 

Also, the console talks about how the images are missing for each map. Any fixes known?
