There are a couple of solutions. I have "165.56 MB" in B2
=VALUE(REGEX(B2,"\d+\.\d+")) will return as a number the 165.56.
\d+is one or more digits followed by \. a point followed by \d+ 1 or
more digits again. This always assumes that there is at least one digit
before and after the decimal.
You can check if a valid number is returned and if not substitute 0.
=IF(ISNUMBER(VALUE(REGEX(B2,"\d+\.\d+"))),VALUE(REGEX(B2,"\d+\.\d+")),0)
You could check if the right 2 letters are MB and if so perform your
substitution
=IF(RIGHT(B2,2) = "MB",VALUE(SUBSTITUTE(B2,"MB","")) ,0)

I have text cells that contain "165.56 MB" or nothing.
I use this formula to get the number:
=VALUE(SUBSTITUTE(C61,"MB",""))
The problem is some of the cells don't contain MB and then return
"Err: 502".
I want to sum the results but the Err: 502 make that fail.
