Solver Runs Infeasible result

Hello I am unable to solve this example. Please seen screen shots and perhaps advice on mistake. It says to check limiting conditions though they look fine to me? What am I doing wrong here?

Hallo
Your screenshot is completely useless without the real file, please attach the .ods-file

hi
just saw this now, thanks for responding attached is the file

NETWORK DESIGN -Lesson 1 Sandy&Co.ods (14.7 KB)

Unfortunately, Calc doesn’t save the Solver’s values, so please tell us what you put in “By changing cells” (it must be a rectangular range of cells).
Also, I think that the Limiting Conditions are only valid for individual cells, not ranges.

Hello Steph

I must have forgotten to include that screenshot. See attached
