Solver not finding solution

[millhouse123]

I am newbie to solver and trying to solve what I think would be a very simple problem but solver is cant find a solution and I can't figure out what I am doing wrong. There is clearly a soltiom which I included in the mini sheet.


Here are my solver constraints. I have tried everything I can think of but still get non solveable.

	A	B	C	D	E	F	G	H	I	J	K	L	M	N
1	Contraints
2	B8:D10	Integer, value must be between 1 and 3
3	Totals for rows and columns need to = 6
4	L8:L10 = 3
5									Counting occurences of each # by activity, should only be 1 activity per hour and should be different each hour
6
7		Activity 1	Activity 2	Activity 3					Activity 1	Activity 2	Activity 3
8	Hour 1	1.00	3.00	2.00	6.00	=	6.00		3	1	1	5	=	3
9	Hour 2	1.00	1.00	1.00	3.00	=	6.00		3	1	1	5	=	3
10	Hour 3	1.00	2.00	3.00	6.00	=	6.00		3	1	1	5	=	3
11		3.00	6.00	6.00
12		=	=	=
13		6.00	6.00	6.00
