I have maintained a excel sheet where in column A there are list of all parameters for a particular product, and again in column D there are few parameters which i require to choose from set of all the parameters in column A.
Is it possible in vba to trigger a click event where it should compare between column A and column D and select the checkboxes automatically if it finds the parameter.
Any help is appreciated!

Worksheet_Change-Event. Could you maybe describe, why you would want the checkbox to be selected? It would be fairly easy to use a worksheet-formula to output yes/no depending on whether the parameter is part of the parameters name list
