Hello Soumendu.
Not the multiplication sign. Please, the 'plus' is the right replacement there. The curly braces {} are using only for enclosing the (all) VALUE expression.
E 2 10 value={(q/Ceq)*(Nsil*(exp(-2*V(2,10)*ET)-exp(V(46)))/(exp(-2*V(2,10)*ET)+exp(V(23))*exp(-1*V(2,10)*ET)+exp(V(46))))
++{(q/Ceq)*(Nnit*(exp(-1*V(2,10)*ET))/(exp(-1*V(2,10)*ET)+(Kn)*exp(V(23)))))}
... or You can use (as example) the next lines:
E 2 10 VALUE {
+ (q/Ceq)*(Nsil*(exp(-2*V(2,10)*ET)-exp(V(46)))/
+ (exp(-2*V(2,10)*ET)+exp(V(23))*exp(-1*V(2,10)*ET)+
+ exp(V(46))))+((q/Ceq)*(Nnit*(exp(-1*V(2,10)*ET))/
+ (exp(-1*V(2,10)*ET)+(Kn)*exp(V(23)))))
+ }
The mismatched parentheses warning during simulation are also corrected.
Also, I hope it will work from now.
Best regards

Hi and sorry. I made a mistake in previous post:
++{(q/Ceq)*(Nnit*(exp(-1*V(2,10)*ET))/(exp(-1*V(2,10)*ET)+(Kn)*exp(V(23)))))}
correction:
++((q/Ceq)*(Nnit*(exp(-1*V(2,10)*ET))/(exp(-1*V(2,10)*ET)+(Kn)*exp(V(23)))))}
