Formula Too Long

[VBAAccountant]

All,

I have an excel formula that currently works but is extremely long:

+IF('Instructions-START HERE'!$E$12=1,+IF(SUMIFS('Full Data Drop'!H:H,'Full Data Drop'!U:U,'PR HD Upload'!B448,'Full Data Drop'!T:T,'PR HD Upload'!F448,'Full Data Drop'!R:R,'PR HD Upload'!E448,'Full Data Drop'!Y:Y,'PR HD Upload'!M448,'Full Data Drop'!L:L,'PR HD Upload'!R448)>0,+ROUND(SUMIFS('Full Data Drop'!H:H,'Full Data Drop'!U:U,'PR HD Upload'!B448,'Full Data Drop'!T:T,'PR HD Upload'!F448,'Full Data Drop'!R:R,'PR HD Upload'!E448,'Full Data Drop'!Y:Y,'PR HD Upload'!M448,'Full Data Drop'!L:L,'PR HD Upload'!R448),2),""),+IF(SUMIFS('Full Data Drop'!O:O,'Full Data Drop'!U:U,'PR HD Upload'!B448,'Full Data Drop'!T:T,'PR HD Upload'!F448,'Full Data Drop'!R:R,'PR HD Upload'!E448,'Full Data Drop'!Y:Y,'PR HD Upload'!M448,'Full Data Drop'!L:L,'PR HD Upload'!R448)>0,+ROUND(SUMIFS('Full Data Drop'!O:O,'Full Data Drop'!U:U,'PR HD Upload'!B448,'Full Data Drop'!T:T,'PR HD Upload'!F448,'Full Data Drop'!R:R,'PR HD Upload'!E448,'Full Data Drop'!Y:Y,'PR HD Upload'!M448,'Full Data Drop'!L:L,'PR HD Upload'!R448),2),"")).

I am trying to automate the entire file but no sure what VBA code to use that would not result in an error. Any help would be greatly appreciated.
