[R] FD package_dbFD error

[Vesna Gulin]

Hi everyone,

I am trying to conduct dbFD from the FD package, but it keeps giving me 
the same error:

ex1 <- dbFD(sites, traits)
Error in dbFD(sites, traits) :
   Different number of species in 'x' and 'a'.

Ab, bb, Ci.... are species names.
I have tried rewriting the species names so many times and ways, but 
nothing seems to work. I also checked for blank space but can't seem to 
find one. Does anyone have and idea what am I doing wrong?

My data consists of two data frames:
sites
