Hi Guys, sorry for again posting on here but this reoprt will be the death of
me.

I have 2 cells that have the following formlas

IN C45 =IF(ISBLANK(AG149),"",AG149)

IN D45 =IF(B45=1,'Base Data'!$H$52,IF(B45=2,'Base
Data'!$I$52,IF(B45=3,'Base Data'!$J$52,IF(B45=4,'Base
Data'!$K$52,IF(B45=5,'Base Data'!$L$52,IF(B45="pd",'Base Data'!$M$52,""))))))

Both C45 and D45 have no data in and are therefore blank - GREAT


Then in cell AF45 I have the following formula which is linking to both C45
& D45 above (the AF cells referenced in the below formula both have values in
FYI)

=IF(ISBLANK($C45),"",IF((MIN((AF$4-$C45)+1,AF$3)/AF$3*$D45/12)<=0,"",MIN((AF$4-$C45)+1,AF$3)/AF$3*$D45/12))

If there is data in C45 & D45 then the formula works fine. However when both
C45 & D45 are blank I am getting ''VALUE'' returned.

I have to have them blank to enable my sum to work.

Thanks again for anyones help. I really appreciate it.
