Module:Infobox television episode

Script error: No such module "High-use".
This module depends on the following other modules:
Module:Infobox television episode is used to validate parameter values for Template:Infobox television episode and Template:Infobox television crossover episode.
Functions

above_title

{{#invoke:Infobox television episode|above_title}}
Returns the text used for the |above= field of the infobox.
episode_list

{{#invoke:Infobox television episode|episode_list}}
Returns the text used for the |episode_list= field of the infobox.
italic_title

{{#invoke:Infobox television episode|italic_title}}
Returns an {{Italic dab2}} instance if title qualifies. Also returns a maintenance category if conditions are met.
The article's title is italicized if the series name is included in the article's title disambiguation. No italicization happens if one of the following conditions is met:
|italic_title=no is set.
The article's title does not use disambiguation.
No |series= value is set.
The article's disambiguation is not equal or does not include the series name.
The page is added to a maintenance category if the title is italicized and there is already an {{Italic dab}}, {{Italic title}} or {{DISPLAYTITLE}} template.
Infobox parameters checked:
|series=
|italic_title=
validate_values

{{#invoke:Infobox television episode|validate_values}}
Returns the relevant maintenance categories based on the {{Infobox television episode}} values validated.
Infobox television crossover episode function

validate_values_crossover

{{#invoke:Infobox television episode|validate_values_crossover}}
Returns the relevant maintenance categories based on the {{Infobox television crossover episode}} values validated.
