In function timer0_toggle_count': (.text+0x0): multiple definition of __vector_7'

[RICHARD511]

Hi i have a proble with this code, it saids "" In function timer0_toggle_count': (.text+0x0): multiple definition of __vector_7' ""

error compling to arduino uno

Please help

this is the code that im ussing
