Hi Mike,

If “if” is used in the expression, you will need to use the Describe and Evaluate methods.
We’d suggest you to reference the attached sample to implement your functionalities.

*Phenomenon:

if you use a format expression you can use datawindow expression such as :
If(salary>60000, 'Overpaid', 'Underpaid') 
and it displays either Overpaid or Underpaid  correctly.

if you use another column as the format expression you can have formats as the column value such as:
'#,##0.00'
and the format works correctly.

However, if you have:
'If(salary>60000, "Overpaid", "Underpaid") '
as the column value, the format displays: If(salary>60000, "Overpaid", "Underpaid")  rather than evaluating the format expression.







*Reproduce Steps:
create a datawindow that has a value column, and a format column.
enter values and for the format enter and IF statement.
setup the datawindow to use the format column as the format expression value.

try different formats in the format column.  if they are expressions they do not work, but if they are just standard formats they do work.

Remark:
12.5.1 works the same way, and it is possible they all prior versions did too.

this would be a nice enhancement to have the format evaluate.  This would allow for more powerful display options for a drop down when there are multiple rows  that have different drop down list values.
