can anyone resolve this issue.
With the details you provided? No.
You have three sketches that were the inspiration for a fourth sketch, yet you only posted two sketches, and failed to tell us which two of the 4 they are.
The sketch of interest, whatever that is, does something. You failed to describe what it actually does. You expect it to do something, yet you failed to disclose that.
Try posting your code in the code brackets so we can see what you have.
//like this!
This will also make it easy for anyone to see your code at a glance and greatly improve the chance of getting helped.
Also explain FULLY what you are trying to get the code to do. Then we will be able to help you.
It would also help if you posted a screenshot of your error message as well as ALL 3 working codes in the format above.

sir, even i am facing the same issue..the basic idea combining these 3 sketches is that whatever i am able to display in the lcd the same data should be transmitted to the server..actually i am doing an IoT project.
please find the attachment below and resolve this issue asap..
