a more concise formula

Can anyone help to make this formula more concise and shorter, it was design to check a numbers in a range to see if any of them falls into a particular range.

=IF(SUM((COUNTIF(Fund,">11999")-(COUNTIF(Fund,">12999"))),(COUNTIF(Fund,">21099")-(COUNTIF(Fund,">28729"))),(COUNTIF(Fund,">28730")-(COUNTIF(Fund,">33999"))),(COUNTIF(Fund,">58999")-(COUNTIF(Fund,">59999"))),(COUNTIF(Fund,">82000")-(COUNTIF(Fund,">84999"))),(COUNTIF(FUND1,">11999")-(COUNTIF(FUND1,">12999"))),(COUNTIF(FUND1,">21099")-(COUNTIF(FUND1,">28729"))),(COUNTIF(FUND1,">28730")-(COUNTIF(FUND1,">33999"))),(COUNTIF(FUND1,">58999")-(COUNTIF(FUND1,">59999"))),(COUNTIF(FUND1,">82000")-(COUNTIF(FUND1,">84999"))))>0,"ATTACHMENT E IS REQUIRED","")

and if the any of the number fall into the range it will print the message, "Attachment is Required"
