Hello group, we meet again:

I have values returned, in Column W25:41; either a number (formatted
as text) or nothing (""), depending on checkboxes selected (Thanks
again to all who helped with that problem before). However, I could
change the "nothing" value if needed... to make this problem easier to
solve.

Next step, I'd like to concatenate these to a singe cell with a comma
delimeter. Problem is, I don't want to include ", , , ," for the blank
values. I know I might have to work with some sort of IF()
statement(s) and either the CONCATENATE() or "&" function, but haven't
quite figured it out. Maybe a LOOKUP() or ROW(), to find the max
value? Those have been my brainstorms, might be on the right track,
might not.

It might be of help to know the last value of actual text in the
column is always the highest number... the highest value possible is
10.

Note, there are a total of 17 rows that might or might not have
values... eliminating too many nested functions.

Yes, this could be done a bit messily by using a series of cells for
reference in between, but I'd like to make this as clean as possible.

Thank you in advance,
Nikki
