I need to figure out how to subtract in service date from current date and return number of days. I think I have just gotten to the brain cramp stage and just can't get by it..... This should be simple but it is just eluding me....
When you say "Form Code," do you mean codebehind (i.e. C#, VB, JScript, or VBScript)? If so, which one are you using?
Just using the standard kit inside infopath nothing special

Our free qRules 1.7 (due out this week) will have a Date Diff function for doing this. So you don't have to write any code.
