項目が増えたり減ったりする表示なら、Accessでなくて表計算ソフトを活用すべきだと思います。

、。

If the display has items that increase and decrease, I think you should use a spreadsheet application rather than Access.

Literal

Items [subject-が] increase-or decrease-or do display [conditional-なら], Access not-being spreadsheet-software [object-を] should-utilize [quotative-と] think.

~たり~たりする lists representative actions: 'increases and decreases (among other changes).' ~べき expresses strong recommendation: 'should.' ~なら frames the condition. 表計算ソフト (spreadsheet software) is the Japanese term for Excel-type applications. A practical tech-support suggestion.
