Changing field color based on Null Variable

[Walter Toney]

ok let me explain this better..

i have a Multi Line Text Field  "Field1"  and i am using that field to Turn the Color of the text and backgroud of another Date Field "Field2" if "Field1" is not NULL

I know i can do it with out code but our requirement is that we need "field1" not being null to turn it 

i have tried the following 

javascript:current.justification_for_urgent_request != "" ;

javascript:current.justification_for_urgent_request != '' ;

javascript:current.justification_for_urgent_request != null ;

javascript:current.justification_for_urgent_request != ;

but nothing seems to be working and i don't fully understand why... any thoughts
