differential equations with conditions

I would like to know how to fix the errors in my code.

syms current(t) 
              eqn = (diff(current,t,2)*L) + (diff(current,t)*R) + (current/C) == 0;
              Dcurrent = diff(current,t);
              cond=[current(0)==0 Dcurrent(0)==8];
              currentSol(t)=dsolve(eqn,cond);

Assign values to L, R and C or declare them as "syms".

Best wishes

syms current(t) R L C 
eqn = (diff(current,t,2)*L) + (diff(current,t)*R) + (current/C) == 0;
Dcurrent = diff(current,t);
cond=[current(0)==0 Dcurrent(0)==8];
currentSol(t)=dsolve(eqn,cond);
