lcd4884 displaying Variables

Hi

How can I display a variable, like temperature changing, on the display.

Using ' lcd.LCD_write_string_big(10, 1, variable, MENU_NORMAL); '
gives me this error:

invalid conversion from int to char

Scale_Menu.cpp:19:19: error: HX711.h: No such file or directory
Scale_Menu.cpp: In function 'void display_weight()':
Scale_Menu:371: error: invalid conversion from 'int' to 'char*'
Scale_Menu:371: error: initializing argument 3 of 'void LCD4884::LCD_write_string_big(unsigned char, unsigned char, char*, char)'

THANKS
