Applying Formulae to Filtered Data

[slh10320]

I have a spreadsheet with formulae that I'm now trying to modify to only apply to filtered data. I've done the simpler AVG and SUM formulae (via SUBTOTAL and SUMPRODUCT) but I have two I just cannot figure out.

{=SUM(IFERROR(--LEFT(J4:J999;FIND("m";J4:J999)-1);0)) &"m - "&SUM(IFERROR(-SUBSTITUTE(MID(J4:J999;FIND("-";J4:J999);99);"b";"");0))&"b"}

and

=IFERROR((SUMIF(M4:M999;">0";L4:L999)+SUMIF(M4:M999;"<0";L4:L999)+SUM(M4:M999))/(SUMIF(M4:M999;">0";L4:L999)+SUMIF(M4:M999;"<0";L4:L999));"N/A")

Any help on either or both will be much appreciated

Hi and welcome to the foum

what formula did you use?

It may be easier to understand what you are doing if you attach a sample workbook. Make sure there is just enough data to make it clear what is needed. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are demonstrated, mock them up manually if needed. Remember to desensitize the data.
