Going back to “VLOOKUP WEEK 2012” Mike ‘ExcelisFun’ Girvin and Bill ‘MrExcel’ Jelen look at the ‘LOOKUP’ Function. Taking cues from an email Bill received from Dan Bricklin [co-founder/inventor of VisiCalc] Bill argues the point that “=LOOKUP” is ambiguous in Microsoft Excel when the Data Set Table is ‘square’. Mike, on the other hand, thinks that “=LOOKUP” is not an ambiguous Function in that scenario; that it is intuitive and dynamic. Follow along with Episode #1550 to hear the debate and decide for yourself.

Today it’s the opposite scenario, where you identify a value in the table and you lookup the value’s row header, column header, and while we’re at it, the address of the value. In the picture, the maximum number is identified, with its address, and header labels for Month and Salesperson.” …To Read More Click Here to go to Tom Urtis’s Lesson.
“Converting color bands to the equivalent resistance value is a good example of how table lookup function can be employed. Anyone can pick a separate color for every band through a drop-down list (built from data validation facility) and Excel matches color selected to the reference table, counts and displays the resistance value.” To Read More Click Here to go to Beginning Excel’s Lesson.
