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
