Maybe change the order of things so you're not trying to round up that ""
string:

=if(iserror(g52*c53),"",if(g52*c53=0,"",roundup(g5 2*c53,0)))

I'm not quite sure why you need that extra =round() in your formula, though.

Hello,

The following formula works great, except when the cell it's referencing is
blank, then I receive #VALUE. What do I need to do in order to fix this
issue? Thanks in advance for the help.

=ROUND(IF(ISERROR(G52*C53),"",IF(G52*C53=0,"",ROUN DUP(G52*C53,0))),0)
