Thanks for your reply Biff
Dave has given a solution using VBA.
I was thinking along your lines.
The spreadsheet is a copy of how quantity surveyors are used to noting their
material lists
it would be messy if they needed to insert an unknown number of extra rows
as the number of various lengths varies.

Hi!

You can't "build" a formula like that although it is possible to calculate
the resulting TEXT string but the formula needed to do that would be a
mile long and EXTREMELY difficult to maintain.

So, I have to ask, why are you wanting to do this? Why not put the values
in separate cells?

I have a list of quantites in one cell "D4"
"D4" = 6/6 3/2.6 5/1.2.
I need to sum each of these to a total so I use the following formula
=SUBSTITUTE(SUBSTITUTE(TRIM(D4),"/","*")," ","+")
Result: "6*6+3*2.6+5*1.2"
How can I convert the result to a formula that would show the sum 49.8

Thanks for any help.
