Macro: Get Values from Multibox

[#1]

Hello,

in a macro I want to retrieve the values from a Multibox.
Typically I loop through the rows, use GetField and retrieve the data using GetPossibleValues or GetselectedValues for that field.

Fine.

Now I have 1 row in the Multibox, which is not a field, but an expression, i.e. a list of values generated by 2 fields.

Let's say fields LastName, FirstName.
The multibox row is defined as Expression =FirstName & ' ' & LastName

Using GetField fails.

How to retrieve selected and possible values?

Thanks in advance,
Thilo
