Have fields from a table in a dropdown to populate a variable?

Hi,

How can I make a dropdown select (input box with constraint on predefined values in Drop-down) that has its list populated from a table? Cheers.

Choose Predefined Values in Drop-down and enable the option Listed Values and enter an expression to created a comma separated list: =concat(distinct MyFieldHere, ',')
