in sharepoint, i have two lists
1. master_company which contain two columns ComCode & Company_name
2. master_project which contain project_id, Project_Description, lookup column from master_company "ComCode"
I insert dropdown list ComCode and project_id. if the ComCode select "abc" then project_id will filter: "PL" & "PL1"
if the ComCode select "xyz" then project_id filter: "TK" into dropdownlist.
Unfortunately, it doesn't work.
see if this helps:
