A IF(istext) formula that needs a trimming, please help?

Hello,

Am really struggling with a IF(is text) formula, it works its just really large and I need to be able to trim it a bit as I need to replicate this formula for several columns its a nightmare, here it is:

=if(istext('Request Log'!B54),'Request Log'!B54,if(istext('Request Log'!B53),'Request Log'!B53,if(istext('Request Log'!B52),'Request Log'!B52,if(istext('Request Log'!B51),'Request Log'!B51,if(istext('Request Log'!B50),'Request Log'!B50,if(istext('Request Log'!B49),'Request Log'!B49,if(istext('Request Log'!B48),'Request Log'!B48,if(istext('Request Log'!B47),'Request Log'!B47,if(istext('Request Log'!B46),'Request Log'!B46,if(istext('Request Log'!B45),'Request Log'!B45,if(istext('Request Log'!B44),'Request Log'!B44,if(istext('Request Log'!B43),'Request Log'!B43,if(istext('Request Log'!B42),'Request Log'!B42,if(istext('Request Log'!B41),'Request Log'!B41,if(istext('Request Log'!B41),'Request Log'!B41,if(istext('Request Log'!B40),'Request Log'!B40,if(istext('Request Log'!B39),'Request Log'!B39,if(istext('Request Log'!B38),'Request Log'!B38,if(istext('Request Log'!B37),'Request Log'!B37,if(istext('Request Log'!B36),'Request Log'!B36,if(istext('Request Log'!B35),'Request Log'!B35,if(istext('Request Log'!B34),'Request Log'!B34,if(istext('Request Log'!B33),'Request Log'!B33,if(istext('Request Log'!B32),'Request Log'!B32,if(istext('Request Log'!B31),'Request Log'!B31,if(istext('Request Log'!B30),'Request Log'!B30,if(istext('Request Log'!B29),'Request Log'!B29,if(istext('Request Log'!B28),'Request Log'!B28,if(istext('Request Log'!B27),'Request Log'!B27,if(istext('Request Log'!B26),'Request Log'!B26,if(istext('Request Log'!B25),'Request Log'!B25,if(istext('Request Log'!B24),'Request Log'!B24,if(istext('Request Log'!B23),'Request Log'!B23,if(istext('Request Log'!B22),'Request Log'!B22,if(istext('Request Log'!B21),'Request Log'!B21,if(istext('Request Log'!B20),'Request Log'!B20,if(istext('Request Log'!B19),'Request Log'!B19,if(istext('Request Log'!B18),'Request Log'!B18,if(istext('Request Log'!B17),'Request Log'!B17,if(istext('Request Log'!B16),'Request Log'!B16,if(istext('Request Log'!B15),'Request Log'!B15,if(istext('Request Log'!B14),'Request Log'!B14,if(istext('Request Log'!B13),'Request Log'!B13,if(istext('Request Log'!B13),'Request Log'!B13,if(istext('Request Log'!B12),'Request Log'!B12,if(istext('Request Log'!B11),'Request Log'!B11,if(istext('Request Log'!B10),'Request Log'!B10,if(istext('Request Log'!B9),'Request Log'!B9,if(istext('Request Log'!B8),'Request Log'!B8,if(istext('Request Log'!B7),'Request Log'!B7,if(istext('Request Log'!B6),'Request Log'!B6,if(istext('Request Log'!B5),'Request Log'!B5,if(istext('Request Log'!B4),'Request Log'!B4,if(istext('Request Log'!B3),'Request Log'!B3,'Request Log'!B3))))))))))))))))))))))))))))))))))))))))))))))))))))))

Basically, what is does is if the value from B54 is available then it is placed in another sheet's cell if there is no value on B54 then it will place the value of B53 and so forth.

Thank you for your help
