concatenated string values

CONCAT(value1, value2, ...)

CONCAT({{name}}, ' with id: ', {{national_id}})

Returns the concatenation of the string values.
Add line breaks with '\n' - e.g. concat('Hello', '\n', 'Goodbye') gives:
Hello
Goodbye

STRING-LENGTH('Test')=4

return the length of a non-empty string

concatenate values with a separator

JOIN(separatorString, value1, value2, ...)

CONCAT('The answers are: ', JOIN(', ', {{question1}}, {{question2}}))

returns the concatenation of the answers using the first argument as a separator

concatenate repeat answer with a separator

JOIN(separatorString, repeatvalue)

CONCAT('The products ordered are: ', JOIN('\n',
{{prodname}}))

returns the concatenation of the repeated answer using the first argument as a separator.

Notes

not

NOT(expression)

NOT({{select1}} = 'c')

as long as 'c' is not selected in the specified Choices question

and

AND

if name has a value, return name, else return national_id

at least X of, at most X of

CHECKLIST(min, max, v1, v2, v3, ..., vn)

CHECKLIST(min, max, v1, v2, v3, ..., vn)

v1 through vn are a set of n yes/no answers. return true if the count of 'yes' is between min and max, inclusive. min or max may each be -1 to indicate 'not applicable'.
