Summary of schedule showing error

[Simbor2]

Hi,

I have a schedule workbook that I have been working on and improving for some time.
On a month summary I earlier had it showing the time worked total including the break because I couldn't work around that.
I had the errors then hidden with "IFWRONG" + ""
Having data coming from another page and then subtract the breaks is something I can't seem to do.

Does anyone have a solution?

It's not clear what your question is.

If you just want to suppress the error values, you could wrap in IFERROR, e.g.

=OMFEL(OM(I8-H8>4/24;I8-H8-0,75/24;I8-H8);"")
