Several variables can sit in a single text element, mixed with fixed text. The whole line is treated as one element and sized as one.
Combining variables
{First Name} {Last Name} produces the full name from two columns, with a space between them.
Any surrounding text is preserved exactly, so Presented to {First Name} renders the fixed words and the value together.
Why this beats separate elements
A single element is sized and positioned as a unit, so auto-layout fits the whole line rather than each part independently. Two adjacent elements can collide when one row holds an unusually long value.
Combining with fallbacks
Each variable in the line can carry its own fallback chain. {Nickname||First Name} {Last Name} prefers a nickname where one exists.
Checking the result
Preview Mode shows the longest entry in the data, which is where a combined line is most likely to overflow the plate.
