UPDATE: It was in fact not my script's fault, he didn't include it properly in functions.php... Anyway, got paid €25 extra for fixing it for him and helped him out with some CSS. So everybody is happy :)
So I made a little simple jQuery script to show a div and picture when clicking on a picture.
My 'client' said he had a jQuery job and I was like, hey I can do it for ya.
So after a little chat we agreed that I would make the script for 25 euro and just email him the script, so he could impliment it himself.
So I made the script in 5 minutes, made a little example page, showed it to him and all was fine.
I get paid, he has the script.
Now when he tried to impliment the script in WordPress, it didn't work. So he contacted me and I'm like oh let me have a loot. So I changed it a little bit, like replacing '$' with 'jQuery' and all that.
It still does not work.
I don't have access to his WordPress installation or whatever so I am just like, try this and maybe than this.
Now, I don't know if I should still continue to help him. Our agreement was that I would make the script and he'll impliment it. Is it my responsibility to make it work within WordPress and troubleshoot his whole WordPress installation and what not, to make it work.
The script worked just as a standalone, but withing the WordPress eviroment it doesn't.
My heart is like "help him fix it, you made the script but you also should help him make it work", while my brain is like "No you did what you agreed to do, and you got paid to do that. It is a waste of time to help him, because you're not getting paid extra".
Can anybody maybe shed some light on what the best way is to handle this and if I'm an asshole if I tell him like hey I did what I had to do.
