hey Lee, sadly there isn't a way to do this currently, but perhaps the could filter out by the columns that display error on the formula results or, a workaround could potentially be:
- 1.
export your table to a CSV
- 2.
edit it with Excel or sheets to assign a number to each column
- 3.
make a new Clay table without the enrichments, only your raw leads data and the new numerated column
- 4.
Use Clay's lookup function to search for the numbered column on your Main table and map it, then you'd be able to filter based on the row number.
