Most likely, you omitted a quotation mark around a string, or a comma at the end of something, or a bracket around a table key. For example, what should be this:
Code:
["You broke it!"] = "Tú lo rompes!",
Currently looks like this:
Code:
["You broke it!" = "Tú lo rompes!",
Or this:
Code:
["You broke it!"] = "Tú lo rompes!"
Or this:
Code:
["You broke it!" = Tú lo rompes!",
Look at lines 184 and 185 in the file named in the error message. The problem is probably on one of those lines.
If you were modifying stuff other than localization, post the section of code around line 185.
