I need help getting this function to work or an alternative
=SUMPRODUCT(--SUBSTITUTE(TEXT($O$12,$O$16,"0.00"),".",":"))

If you put the two cells inside parentheses, you create a union of them. You can then refer to different areas within that union using INDEX function:
INDEX(($O$12,$O$16,,,1)         returns a reference to the first area ($O$12)
INDEX(($O$12,$O$16,,,2)         returns a reference to the second area ($O$16)

You can use this method in a SUMPRODUCT as:
=SUMPRODUCT(--SUBSTITUTE(TEXT(INDEX(($O$12,$O$16),,,1)+INDEX(($O$12,$O$16),,,2),"0.00"),".",":"))

The same approach will also work in a SUM formula with regular entry:
=SUM(--SUBSTITUTE(TEXT(INDEX(($O$12,$O$16),,,1)+INDEX(($O$12,$O$16),,,2),"0.00"),".",":"))

This approach is admittedly not very impressive for a non-contiguous range of two cells. It gets a lot more interesting if you expand it to non-contiguous columns of cells, such as in this thread:

My previous suggestion was incorrect. It did the calculations in the wrong order--first adding the numbers, then performing the text manipulation.

Try either of the following instead:
=100*(MROUND($O$12,0.01)+MROUND($O$16,0.01))/1440
=(MROUND($O$12,0.01)+MROUND($O$16,0.01))/14.4

With the correct ordering of operations, my first suggestion should have been:
=SUMPRODUCT(--(SUBSTITUTE(TEXT(INDEX(($O$12,$O$16),,,1),"0.00"),".",":")+SUBSTITUTE(TEXT(INDEX(($O$12,$O$16),,,2),"0.00"),".",":")))

For a two-cell range, the MROUND approach is much simpler.

excellent.just another question if it's only one range as in
=SUMPRODUCT(--SUBSTITUTE(TEXT($O$12,"0.00"),".",":"))
is there an option that can handle one or more ranges.

Could you please explain the real problem you are trying to solve? String functions like SUBSTITUTE are less flexible than you might wish in array formulas such as SUMPRODUCT.

I have posted two formulas that can be expanded to one or more ranges:
=(MROUND($O$12,0.01)+MROUND($O$16,0.01))/14.4       good for single-cell ranges
=SUMPRODUCT(--(SUBSTITUTE(TEXT(INDEX(($O$12,$O$16),,,1),"0.00"),".",":")+SUBSTITUTE(TEXT(INDEX(($O$12,$O$16),,,2),"0.00"),".",":")))      good for multi-cell ranges

It may be, however, that your real problem is best solved using a different approach.
