Concatenate two fields one is a user the other field is a date field

List("_", ToText([My Date field]), UserToName([My User field]))

Thanks, what if I want to concatenate a field with a work for example
List("_",ToText(My Date field])," Pass")

Sorry, can you give an example of the result you want?  The first parameter in the quotes is the separator, and then the rest of he values are what gets listed, separated by he separator.

Can you use a list with numeric fields
