Dynare syntax error, unexpected ';'

Hello, when I want to run the model I am working on I get this error referring to the following line:

0=((1-EPSILON_H)+(exp(mc_H))*(EPSILON_H)-(phi_R)*(((exp(p_H))/(exp(p_H(-1))))-1)*((exp(p_H))/(exp(p_H(-1))))+(exp(R(+1)))*(phi_R)*(((exp(p_H(+1)))/exp(p_H))-1)*(((exp(p_H(+1)))/exp(p_H))^2)*((exp(y_H(+1)))/(exp(y_H)));

The error is: "Dynare syntax error, unexpected ‘;’ "

I would appreciate if someone could help me notice what causes the error and correct it.
Thanks!

The very first bracket never closes.
