how to use vlookup with conditional formating

hi all my friends,
i need your help in this case, i want to make conditional formating for a row in a table when i write the value of one its cells, and repeat this conditional formatting for entire table when i write the value in the entire column, i tried to use vlookup several time but i doesn't work properly
in this case i want to highlight entire row in table ( b7:i100) when i choose value in column k.
