I am using InfoPath 2010. I have a date picker that is for first day of week. Unfortunately I also have users that will sometimes pick a day other than Monday. I have seen instructions for how to restrict the day for IP 2007 (bizsupportonline.net/infopath2007/force-select-day-of-week-date-picker-infopath-using-rules-formulas.htm]Forcing users to select a particular day of the week from a date picker in InfoPath using rules and formulas - BizSupportOnline[/url]), but was unable to convert those instructions to 2010. Does anyone know how to do this?
