Custom field and two conditions

[PMM]

Hi,

I'm trying to create a custom column that checks the field "language" for the string "eng", then uses the series name. However, if series_index is 0 or lower, it should not show the index number—only the series name.

I came up with something like this. Can you help me?

{languages:'in_list($, ",", "eng", "{series:|(|. }{series_index:|Book |)}", "")'}

{languages:'in_list($, ",", "eng", "({series:|(|. })","")'}
{series_index:'in_list($, ",", "0.", "{series_index:|Book |)}","")'}
{series_index:'in_list($, ",", "0", "","{series_index:|Book |)}")'}
