I am in need of summarizing responses to questions based on the respondent
marking their selection in column A with an X. I am assuming that an array
formula would do it for me. I want to concatenate the responses selected in
column A into column C (any row), not include any blanks (choices not
selected with the X) and separate each response with a comma. So it would
look like this: small group, tutorial, one on one training. Is an array
formula what I need? If so, how would I write it?

TIA for your help
