If you want the chapter to be only view-able if the player meets the requirements, you can simply set the conditions to view the chapter accordingly (simply enter all of the values).
If you want to display it within a chapter itself, when the requirements are not certain to be met, you need to nest quite a lot of statements like this, not with "elseif", but with several "if" statements:
Code:
{if Charisma Skill < 60}
{if Combat Skill < 60}
{if Gambling Skill < 60}
{if Sex Skill < 60}
{if Stealth Skill < 60}
Monika is a jack of all trades.
{endif}
{endif}
{endif}
{endif}
{endif}
The logic will check for the first IF, and only if that is met for the second IF, and so on. Basically this is your AND combination, only really ugly ;-)
I tried the following, but it doesn't work:
{if Charisma Skill < 60}
{elseif Combat Skill < 60}
{elseif Gambling Skill < 60}
{elseif Sex Skill < 60}
{elseif Stealth Skill < 60}
{else} Monika is a jack of all trades.
{endif}
I have the feeling I am missing something obvious.
What your example does, is to check for the "Charisma Skill < 60". And if that condition is met, it will display some text (however there is none in your example), and not check for anything else. That way, the {elseif x} statements will not be processed and the statement will finish and go to the {endif} right away.
In your example "Monika is a jack of all trades." will only be displayed, if none of the conditions are met, i.e. if all of her skills are at least 60
