Hi,
table[1] is the first index of a table. Its value is the string 'Color: Orange'
Here i'm trying to just get the word 2 characters after the ':', using string.find then string.sub
firstkey = table[1]
pos = string.find(""..firstkey, ":") -- Position of ':'
after = ( string.sub(""..firstkey, pos+2) ) -- Everything from two characters after ':' onwards
print(after)
It doesn't work though, and the output says that it expected a string for string.find, instead it got a table.
Why is this and how can I fix it?
Thanks in advance.

Can you show us what the variable table is? That might help determine the problem.
It's not the problem - print(table1) prints Color: Orange
I don't get it. Works perfectly for me if I replace table[1] with "Color: Orange". What are the contents of table?
It's just [1]=Color: Orange, [2]=Color: Blue, [3]=Color: Green etc..
fyi, those should be surrounded by by quotes or [[]] (e.g. table = {[1] = "Color: Orange", [1] = "Color: Green"} etc.) Consider storing the name of the color itself without the "Color: " part.
For the sake of writing the table in the comments, I simplified it, and I am also unable to change what it's stored as because i'm working with someone else's table.
Mind pasting the full table in the comments? No simplification, please.
I don't exactly HAVE the table - i'm reading it.
I ran this code: http://hastebin.com/ayalejayat.lua It works as expected. There's something wrong with your table. Ask whoever wrote the table how they formatted it. You may want to do something like
for i, v in pairs(table) do print( i, v ) endto check how the table is formatted yourself.Will do - thanks!
