Expected } (to close '{' at line 1) got 'PLACEHOLDERFORHELP' How to fix?

Hey! I don't know what I'm doing wrong, but it says that it expected me to close the brackets at a specific line, and adding more code to that line kills the script! I've done everything!

    local module = {
          
      PLACEHOLDER = {Page1 = {"placeholder", "placeholder"}}
      PLACEHOLDERFORHELP = {Page1 = {"Placeholder", "Placeholder"}}

    }
    return module

Hey, just add a comma and you fixed it! Example:

local module = {

  PLACEHOLDER = {Page1 = {"placeholder", "placeholder"}},
  PLACEHOLDERFORHELP = {Page1 = {"Placeholder", "Placeholder"}}

}
return module
