Question:How do I deal with a lcoeff or tcoeff, tools/sign error

The time derivative problem I had earlier is solved, thanks very much, except for the equation below:

diff(x3, t) = 2*lambda*a(1-p)*[x1*(x1-1)+x2*(x2-1)]-2*a*p*x3*[x2+2*(x3-1)]-2*delta*x3

which I seek to solve using:

dsolve(diff(x3(t), t) = 2*lambda*a(1-p)*[x1*(x1-1)+x2*(x2-1)]-2*a*x3(t)*p*[x2+2*(x3(t)-1)]-2*delta*x3(t));

Somehow the following error keeps coming back:

"Error, (in tools/sign) invalid argument for sign, lcoeff or tcoeff"  which i cannot find in maple help,

any suggestions?

Kind Regards
