Set multiple field values

[nickedw0]

I have a list box with month names :Jan Feb Mar,...,Dec

I have a trigger that set the value for the Month field:

Action: Select in Field

Field: Month

SearchString: Month(vDate)

If vDate is 07/10/18, 'Jul' is selected.

or Month (AddMonths(vDate,-1)) selects 'Jun'

How can I select both Jul and Jun?

Use two actions. The first action is select in field.

The second is toggleSelect
