Hello

frist dropdown list
with 2nd dropdown list attahed are user names.
I can see the both (in sharepoint workflow forms), but i need to cahge the
names in 2nd DDlist on the basis of selected office in 1rst DDlist.

Means changing value of DD list on basis of selected value of other DDList.
How can i do that, please help.
