Solver- lock a cell

Hi,

I've build a solver with many conditions.

The calc is performed on a list, with 80 items.

It returns the combination of 8 items, under the conditions.

If i want to "lock" items, that no matter what the result is, they have to be inside, how do i do it?

Many thanks.

Upload an example of the spreadsheet, impossible to understand what you want..

attached per your request

It's really uncreal in o1:r11 what you are calculating. Do you mean simply locking the range with $?

i want the max amount of points (Q1)
Under 200 cost (Q2)
With 8 items (Q3)

Items are "B" column, Calced binary on "G"

My question is that if i want "b3" item (KYL) to be in the end combination, how can i lock it to be there?

Sorry mate, but I have no idea what you want.. G columns has all values as 0.
