Hello every one ,
please can you help to find an program can copy the content digit writing in the Lcd by user with an keypad in an variable :for example if an user write 1500 in the Lcd how can I put it in an variable"X" and thank you in advance.

That would depend a lot on:

  1. Which LCD
  2. Which keypad
  3. Which program

for example if an user write 1500 in the Lcd

The user can't write 1500 in the LCD. Only the Arduino driving the LCD can do that. Since YOU control the code, YOU have full control over the data you write to the LCD. It is either already in a variable or is a string literal.

That it is not in the variable that you want it in is obvious. Where you want it, what it is, and how to get it there are not at all obvious.

In other words - post the program that is causing the problem and explain what it actually does and what you want it to do.
