If I understand your requirement properly, create a calculated field using the following syntax:
Case [Parameter name]
when "1" then "January"
when "2" then "February" ~etc
Then insert this calculated field into your text box
Thanks. Is there no date function that will convert a number into a month?
But "1" isn't really a date, does 1 mean the first month of this year ? calendar year or fiscal year ?
You can take the "1", and add in the other values as part of the MAKEDATE function, but why not just have the user choose the date in the parameter ?
