3. 3. What is Lookup?<br />In Excel, the Lookup function returns a value from a range (one row or one column) or from an array. <br />Lookup is the simple function to return the value from a specific range. <br />This function looks for a piece of information in a list, and then picks an item from a second range of cells.<br />=LOOKUP(WhatToLookFor,RangeToLookIn,RangeToPickFrom)<br />The WhatToLookFor should be a single item.<br />The RangeToLook in can be either horizontal or vertical.<br />The RangeToPickFrom must have the same number of cells in it as the RangeToLookin.<br />Be careful not to include unnecessary heading in the ranges as these will cause errors.<br />Saturday, September 25, 2010<br />An introduction to Microsoft Excel<br />
