We have a selection box (Company) with four possible selections (say 'ABC','DEF','GHI','JKL'). I have a text box that reads the selection and uses it concatenated with 'Report' to provide a header (=Company & ' Report').
So selecting 'ABC' produces a text box with 'ABC Report' etc.
However we select two specific Company selections, say 'DEF' and 'GHI' I want the text box to say 'MNO Report'.
=if(GetCurrentField(Company) ='DEF' andGetCurrentField(Company)='GHI,'MNO',Company) & ' Period Report'
