Question: help, new to maple getting error invalid specification of initial conditions

hello, im trying to numericaly solve this differencal equaion and i cant see what the issue is with my boundery condions. the only thing i can guess at is the bondrey conditions are ant the limits of the range im intergrating over. any help would be amazing

E := -2;

                                     -2

> DE := -(1/2)*(diff(diff(F(x), x), x))+(x^4-3)*e^(-(1/2)*x^2)*F(x) = -2*F(x);

                                        
            1  d  / d      \   / 4    \  \- 1/2 x /              
          - - --- |--- F(x)| + \x  - 3/ e           F(x) = -2 F(x)
            2  dx \ dx     /                                     

> ini := F(-5) = e^(5*(-2*E)^.5), (D(F))(-5) = e^(5*(-2*E)^.5)*(-2*E)^.5;

                         10.00000000                                                10.00000000
          F(-5) = e                        , D(F)(-5) = 2.000000000 e          

> dsol := dsolve({DE, ini}, F(x), numeric, range = -5 .. 5);

Warning, The use of global variables in numerical ODE problems is deprecated, and will be removed in a future release. Use the 'parameters' argument instead (see ?dsolve,numeric,parameters)
