Changing an integer to a month

[tjcinnamon]

I have a form that asks what month you completed a file (04, is april ect.). In my report I have it read this number and I want it to display the month for the number thats entered (if they enter 04 I want april displayed on the report). There is already a ton of data that has the MonthCompleted as 04, so changing that is out of the question.

Thanks, JOe K.
