# Access special fields in especies list

Asked by lcomas on 2018-12-02

Hi OF Team

I am interested to access fields of taxon attribute that are not visible in the user interface and that i had added to especies list. For example, i want to count de number of exotic species detected in a plot. I add this field in the especies list, but how i can use it? It is possible?

Regards,

Lluís

Hi Lluís,

If I understand the question correctly,You need this formula:

idm:speciesListData("SPECIES LIST NAME", "column name from species list", TAXON ATTRIBUTE NAME) 

At first, create calculated Text or Number (Depending on what is written in the column) attribute and uses this expression.

Best regards
