I have a file that has a date format of MM/DD/YYYY in a field that i am reading. I have found that i am unable to either find or do some sort of comparison between a Date field and that. What i am really after is just to compare the Day of the Month 1-31 to the DD in my String. Suggestions (with examples). I was able to get my expression to work if I changed my file to just have the DD in it, so i am trying to find out a way to get the expression to look at the DD between "/"DD"/"
