Hello, I'm trying to find a macro for couting the number of instances of a text string, then export the results to a txt doc.

We are looking to move to offsite printing, and will be merging all of the documents to one file, and there will be a trigger to advise of different mailings. The goal of the macro would be to count how many instances of that trigger there are and export it into a txt file so that we can track how many individual documents were sent to them
