Hello
In the sheet named "ADJ FORMAT" select the range B10 to P11 then go to Home tab and Conditional Formatting and 'New Rule' >> Select 'Use a formula to determine .....' and type that formula
Code:=NOT(ISNUMBER(MATCH($P10,CHECK!$D:$D,0)))
Then click 'Format' and do the formatting task as you wish (Fill tab for example and select any desired color) and finally click 'OK'
