Filtering One Drop down box based on the value of another drop down box


I have two fields - one Called 'Division' and the other called 'Business Unit'.  There are many business units under each division.  For example:

SP Field: Division:


SP Field: Business Unit:





SP Field: Division:

Public Engagement

SP Field: Business Unit:

Business Unit A

Business Unit B

Business Unit C

Business Unit D

SP Field: Division:


SP Field: Business Unit:

Business Unit E

Business Unit F

Business Unit G

Business Unit H


What I would like to do is select the Division in the drop down box, and the Business Unit drop down field will only display the the records related to that particular Division.  For example, if I pick the division of 'Directorate', then only Business Unit E,F,G and H will be available from the in the Business Unit drop down box.  Both data cards (Division and Business Unit) write back to their respective SharePoint fields.  I have created a separate SharePoint list called Business Unit (which has been added as a data source) with the following info:


Division, Business Unit

Corporate, HR

Corporate, Finance

Corporate , Legal

Corporate, IT

Public Engagement, Business Unit A

Public Engagement, Business Unit B

Public Engagement, Business Unit C

Public Engagement, Business Unit D

Directorate, Business Unit E

Directorate, Business Unit F

Directorate, Business Unit G

Directorate, Business Unit H


Now my question is how do I get the Business Unit field to filter the values from the Business Unit List, then insert the selected value into the original Business Unit field?


Any assistance is always greatly appreciated,




OK I have it working now:



I played around with some settings, and this is the code that worked:


      DropDownBusinessUnitList = ComboBox2.Selected.Result


I have no idea why this works 😀
