Anyone knows how can I insert a polylogarithm function to FORTRAN? I am trying to put Li_2(z) polylogarithm function to my equation.
Thank you in advance.

You'd have to write the function, if you do not have it in a library of functions.
If you need help with the definition of the function, check the following site:
If you have difficulties with writing the function, you can post what you've got, and we will then know how we can help.

A good reference for a polylogarithm function algorithm is the following:

If you are interested please send me an email (firstname.lastname@example.org) and I will then send you copies of the FORTRAN codes I wrote to calculate the dilogarithm and trilogarithm functions of complex argument based on Crandall's algorithm. I've checked them using Mathematica and they work quite well.
