re: Query on observe form and rjs

Hi divya,
do u really require 3 fields for project, type and program.
i will give u one suggestion..
i.e.,
1. use one ajax based dropdown list box for project
2. in that ajax based dropdown list, u can show project names.
3.if u use ajax based dropdown list, u can get type automatically, after selecting
any of the project.
4.use one text box for program.
5.the text box can be initially blank and will populated with the program name
after selecting the project from drop down list.

if these above 5 points matches to ur requirement,
u can reach me through gmail.
my mail id --> [email removed]
then, i will provide u the solution..
