Set lore command not working with multiple lines

[Cohenerickson]

I'm trying to make a lore command to set the lore of an item but I'm having trouble getting it to be multi-line, if anyone could help that would be great.
This is my code:

command /lore [<text>]:
    trigger:
        set lore if players tool to colored arg 1

What I'm typing to try and set the lore is:

/lore line1||line2||line3

This is more easy to do in your case:

command /lore <int> <string>:
   trigger:
       set line arg 1 of lore of player's held item to "%coloured arg 2%"
