Hi All,
I have a basic mileage app with 2 tables, tblVehicles and tblMileageLogs, when you go to the form to log vehicle mileage against a vehicle, you go on a drop down within a form and select the vehicle you want. However it shows both active and none active vechicle because the forumula is Choices([@tblMileageLogs].'Vehicle Reg') within that drop down so it would do.
However i only want the choices of that dropdown to show only the active vehicles only. (The field type is a YES/No (true/false) within a sharepoint list for active within tblVehicles.
I have put some images to help what i am tryign to achieve.


Vehicle Reg in mileage logs is a sharepoint lookup column if you need to know that but i also have it as a text column called Vehicle Reg BI. dont know if you needed to know this part 🙂

Hope you can help me.
