Excel add total of entries separated by a + sign in a formula?

[chris oneal]

I'd like cell E433 to total the amount of entries entered into a formula in cell F433 where the formula is: =91.72+38+292.45+38.4+81.23+43.52. Additionally, the whole E column will use this formula. Cells in F column will either have numerical entries, or will have simply have "N/A". So I'd need it to recognize that as well, and show 0 when that happens.
Any assistance would be appreciated. Thank you.

If each entry is separated by a "+" sign...

=IFERROR(LEN(FORMULATEXT(F433))-LEN(SUBSTITUTE(FORMULATEXT(F433),"+",""))+1,0)
