How to sum a column that has "--" values.

How to sum a column that has "--" values.

Question:

The SUM formula at cell N2 results in "--"

This is because the CONTINUE function in E147 resulting from the VLOOKUP formula in E3 is yeilding a "--" (which is a result of the actions on the HTML Lookup sheet.)

Is there any way to get the sum formula to ignore errors and "--" results and sum the valid numerical results?



Solution:

Instead of =sum(N3:N162) , Try =SUM(FILTER(N3:N162;ISNUMBER(N3:N162)))

So to exclude all non-numerical values, Instead of using formula =SUM(F10:F15), you must use =SUM(FILTER(F10:F15;ISNUMBER(F10:F15)))

I hope this solution will help you out.
