Formula cells not to change once new rows inserted

Hi all

I'm trying to wrap my head around this. I have in a formula in one sheet pointing to a cell in another. Once I insert a row the formula adjusts. I need them to remain static.

I have tried searching, however I'm not 100% on the terminology.

I have tried the F4 shortcut and put the $ signs in, however they still change.

Any ideas? I bet its something simple

Thanks
