COGNOS - Report Studio

In Report Studio is there any way to display an input date in MM-DD-YYYY format? Report Studio has a format property for the texbox but it does not convert the date and seems to ignore the any settings. The report expression of ParamDisplayValue("SEL_START") doesn't seem to work when nested in another report expression.

Is there any way of changing the COGNOS date format when its used as an input value?

Things tried:

1. Using the Format Data Property - I have the Data Format set to "Date" with the appropriate settings on the property sheet.
2. Built in Report Formatting - I've used built-in/pre-created date formatting functions like REPPARAMDATE([SEL_START],'MM-DD-YYYY') and REPGETFMTDATE('EN', [SEL_START])

Thanks. :)
