[support] how to check worker already assigned in the particular date

[bharani kumar]

Hi Experts

How to check ,

The worker already assigned for the particular task with some x leader for
the particular date ,

Here am having the

Date(textfield) ,
Leader name(drop down),
Worker name's(Multiple List box),

or is there any module for that ?

for example

x,y,z are the leader,
a,b,c are the workers

assume a is assigned to x on 15-march-2009

if admin again try to assign the  'a'  worker to y leader for the task , on
15-march-2009 ,

Then need to raise the validation error

Like the a is already assigned,please choose another worker ,

any grate  idea
