Hi Kawata,
I have added a new sequence activity to convert the value to double using invoke method as you suggested and now its working.
I think this step should be added to the framework walkthrough pdf document.
Another issue which I found out is that application which was provide by uipath does not allow decimal i.e. dot to be inserted inside the textboxes and due to which incorrect values are getting inserted.
Thank you for you earlier reply.
