hi I have a a lot of sheets in one excel-file, about 25 upwards , and
in these I fill in the time for each project each person is involved
in. What I want is a sheet with a summary for all the projects. Every
project has a six digit code.

Can I create a formula that searches through the entire project for
example project 440011 and return the value to the sheet where I
summarize all the time?

The problem is that I want the projects to be sorted by the six digit
code but when I sort them in each persons sheet the references in the
summarized sheet will be wrong.

Does anyone understand what I mean? :=)
