Thanks for reply, but really what I need to do is LOOP the FiindRoot below. A1,A2,A3 are input data, in a table k's are pre-defined constants t's are variables to solve and plot. Eqn1 = t1 - k1*Log[ 1 + (A1/A3)*(1 - exp(-t3)*(exp(-t2) ] Eqn2 = t2 - k2*Log[ 1 + (A2/A3)*(1 - exp(-t3/) ] Eqn3 = t3 -k3*t2 FindRoot[{Eqn1==0,Eqn2==0,Eqn3==0}, { {t1,1},{t2,1},(t3,1} } ] Regards, John
