We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Rob, 

Thanks for your reply. 
vof_l = C_VOF(c, tp) and t*tp = pt[2]. Here 2 is the ID for the phase. vof_l is assigned the concentration of phase 2.

In your proposed change, C_VOF(c,t)[0], what does 0 stand for? 1st species in phase 2!?
