hi u can pass parameters into different actions by 
navigating to file in qtp there go to settings tab & click 
on parameters tab where you can specify the name ,type & 
the default value of it..Apply it & use it in your 
script..If you have not understood write to me

I know that what u have explained.But how to use those 
parameteres in a an action.I want the script that how to 
use input action parameters.That is why I already asked 
that I want explanation with examples.
suppose I want to pass 2 values for a,b and would like to 
get the result in "c". see below code 

c=int(a)+int(b)

How should I pass parameters here and how should i write 
the code for passing parameters.How should i call that 
action. give me the detailed exp..

Hi Rayudu,

i will take the example that you have taken.
C = a + b
Now you want a and b to be parameterized.
So for that you have to pass the value of a and b using the 
datatable in QTP.
Select 2 columns in datatable and name them Value_1 and 
Value_2.You can choose either Global datatable or action 
datatable.Suppose you choose Global datatable.
Now put a value say 3 under column Value_1 and put another 
value say 5 under column Value_2.
Now this is how you gonna write it:

c= Datatable.value("Value_1",dtglobalsheet) + 
Datatable.value("Value_2",dtglobalsheet)

Now is this solve your problem? or if you have any further 
queries then just reply...

Thanks for your reply Deepak! But my question is not that.
By using Action Parameters.EX: I would like to enter the 
values in Parameter tab of the Action properties.



Name   type     Defaultvalue      description
A      Number    25               First value
B      Number    30               Second value

My question is How should validate these values in a script
c=int(a)+int(b)
I am calling this action in another action like
RunAction Action1,Oneiteration
But it did not resulted 55.
I know how to pass parameters through datatable.
Please answer it if u know
