Hi All, I have couple of doubts- 1) I have two sets of monthly data (Jan11,Feb11......Dec11) and (Jan12,Feb12.....Dec 12) side by side . I want the summation of the two sets of data under two dfferent headings. For eg- YTD11 and YTD12. 2) I have three sets of data namely sales, volume and units under three diffreent tabs. I want the volume and the units tab to be arranged or sorted just like the sales tab (ie i want only those customers which features in the sales tab?- Thanks
