I am trying to get a variable expression to work using the IIF function. I want to Print a different message based on paged number. Here is my expression that fails. Hopefully someone can help me out.

[IIF(<Page> = 2,'','Continued From page' + [floattostr(<Page>)])]

Thanks in advance.

    here is an example from a memo in a page footer.
    [IIF(<Page> > 1,'continued from Page: ' +VarToStr(<Page> -1),'Page: '+Vartostr(<Page>))]

    user manual, creating reports, topic displaying expressions with the help of the text object.

    select a text object go into edit mode use the expression builder to build the expression in most cases this will set the correct braces for you.
    the reason vartostr() is used is the fact that you are trying to concantenate the variants return value to the string portion assigned to the expressions true or false value.
