Is there a way to have a formula not include a cell that the text has
strikethrough lines?

What I need is if $C$22:$C$375 = abc or = def or = ghi then sum G22:G375
unless strikethgrough has been added to the text by formatting of the cell.

It's the only way I could think of for certain cells to sometimes not be
added up (if the job is sent out rather than done in-plant) without deleteing
the formulas in G22:G375

Any Suggestions?
Thanks!
