What can be wrong with my formula?

[Parra]

Take a look below, what could be wrong with my calculated field? When it tries to run it highlights the first AND. Its says the expression contains an invalid syntax.

Pages:IIF(AND([section]="CLASSIFIED",[description]="inch"),[sumoflinage]/215,IIF(AND([section]="CLASSIFIED",[description]="line"),[sumoflinage]/2795,IIF(AND([section]="display",[description]="inch"),[sumoflinage]/129,0)))

Thanks Parra :x

OK I fixed, just in case you are interested in what I did.

Pages: IIf([section]="CLASSIFIED" And [Inches Or Lines].[Description]="inch",([sumoflinage]/215),IIf([section]="CLASSIFIED" And [Inches Or Lines].[Description]="line",([sumoflinage]/2795),IIf([section]="display" And [Inches Or Lines].[Description]="inch",([sumoflinage]/129),0)))
