make calculations work with one worksheet closed

Is it possible to make formulas work if only one worksheet is open? I am
trying to make some spreadsheets for an elderly person and I have to open
too many worksheets open for it to work. Lets say I have a worksheet
called Quarter. That sheet gets its information from a sheet called
Journal. Once the data is entered into the journal it gets transferred to
the Quarter sheet, but if I open up the Quarter sheet without the Journal
sheet open I just get value in the cells. Can I do something so that the
journal does not have to be opened and still get the info in the Quarter
sheet?
