VBA Excel Macro

Need VBA macro that iterates through range in primary sheet and finds all occurrences of itself in a secondary sheet. For every match, the macro must construct a comma separated & alphabetically ordered list of matches and append it to the same row of matched cell on the primary sheet. For example, per the attached VBA SAMPLE TEMPLATE The master sheet is named MASTER (it contains no duplicates) The secondary sheet is named SECONDARY (it contains many duplicates) The macro follows this logic Starting from the master sheet, it iterates among ever row in the sheet. It gets the value in column B named “ThumbrintLookup”. That value is searched in every row of column B in the secondary sheet For every find, match, it collects the value in column A named “Key” from the secondary sheet It puts the value in column D of the primary sheet It continues to build a comma separated string/list of matches After no matches are found for the processed row, the macro continues to process the next row Notice that column C named count in the primary sheet reports the number of matches that ThumbprintLookup appears in the secondary sheet Therefore the quantity of comma separated strings matched in the secondary sheet MUST match the count value specified in column C of the primary sheet ........................... This is a 10 minute job for a VBA specialist. Keep it simple, scalable and document your code. If proven, we can do more advance work in the future. That's why this is a very low budget project to demo what you know. $10 Max Don't bid for my maximum. I'll review proposals that have the keyword VBAROCKS in their bid :)
