## Question:Error, missing operator or `;`

Maple 2016

Hi,

I am writing the following code and MAPLE is giving me operator error. Please help (file: doubt_6.mw)

d2:=100000000

for m in set_m do
for n in set_n do
SOL1 := fsolve({ODE11, ODE12}, {N, t__2});
N1:=eval(N,SOL1);
t_2_1 :=eval(t__2,SOL1);
T_1:= eval(T, [lambda = 3, a = 300, b = .15, c = .25, A__m = 300, A__d = 150, A__r = 50,C__m = 4, P__m = 8, P__d = 10,
P__r = 12, theta__m = .15, theta__d = .12, theta__r = 0.5e-1, h__m = .2, h__d = .3, h__r = .5, i__m = .1, i__d = .1,
i__r = .1, i__om = .1, i__OD = .15, i__c = .3, i__e = .2, M = 2, alpha = 0.2e-1, t__2 = t_2_1]):
t_31:= T_1 /m ;
t_41:= T_1 /(m*n) ;
if (N1<=t_41 and 2>=t_31) then
d1:= eval(TCS__1, [lambda = 3, a = 300, b = .15, c = .25, A__m = 300, A__d = 150, A__r = 50, C__m = 4, P__m = 8,
P__d = 10, P__r = 12, theta__m = .15, theta__d = .12, theta__r = 0.5e-1, h__m = .2, h__d = .3, h__r = .5, i__m = .1,
i__d = .1, i__r = .1, i__om = .1, i__OD = .15, i__c = .3, i__e = .2, M = 2, alpha = 0.2e-1, t__2=t_2_1, N=N1]):
if (d1<= d2) then
d2:= d1;
print("Value is updated",d2,N1,t_2_1,"for",m,n)
end if
end if
print(N1,t_2_1,t_31,t_41,d1,m,n)
end do
