I am trying to populate two drop-down lists from one Sharepoint list, where the condition is that if in the first drop-down list a value is selected, the secont drop-down list should have the value of the same item(row) form the Sharepoint list. The idea is that if I have a lists with a machines which are build in a factory, they are build with a number and a name(one row). I want in the first drop down to select the number, and in the second one automatically to ricieve its name.. or vice verca.. I don't understand where am I wrong, since when I am using the same technique(using the same data connection, the same filters and so on), but with a one drop-down list and a text box, the box can be populated with the required value! I am very confused, and this requirement I have to fulfill. Can anyone help me!
