I would like to make this unique so the system would prevent the user from creating multiple statuses on the same date for a project. When I try to enforce uniqueness on this field I get the following error message: Here is the formula: ToText([Project - Record ID#]) & Mid(ToText([Status Week Of]),7,4) & Mid(ToText([Status Week Of]),1,2) & Mid(ToText([Status Week Of]),4,2) Here is the error message when I try to enforce uniqueness: ?This formula is incompatible with this field being marked unique. Please change the formula or uncheck the unique checkbox.? How can we meet the requirement underlined above? Let me know if you need further clarity. Re: Logging edits to a recordThanks. Curious about the image onload technique, will wait for the example.Logging edits to a record Is it possible to set up a multi line text field that can log every edit made to a record with the field that was touched, user who did it and a date stamp? How would I specify a form rule to make all fields in a record read only on fulfillment of a condition, without specifying each field individually? The record has about a 50 odd fields.
