Which version of Joomla do you use?

[wmswina]

Joomla! 3.3.1..
and I've just checked that the function is not compatible for Joomla below version 3.4 right?
am I right?

line 294 : $excludeArticles = ArrayHelper::toInteger($excludeArticles);

which part that I should change? kind of confuse.
sorry, I'm still learning in Joomla..

ArrayHelper::toInteger($excludeArticles);

remove "$excludeArticles = "
