Whether it be to look up corresponding items in another question ([[filter-items|Use Selected Items in Another Question]]) or just to check whether at least one item fulfills a particular condition.

| This chapter describes the function ''getItems()'' and so-called loops -- two tools which allow sophisticated filters over multiple items. The starting point of this chapter is the following question TF04: a scale. The scale's values and the item IDs are shown in the image for additional information. | This chapter describes the function ''getItems()'' and so-called loops -- two tools which allow sophisticated filters over multiple items.
