Not same, different.
I am thinking because I then need to include "ProjectsInfoDB"?
Search(ProjectsInfoDB,txtSearch_1.Text,"ProjectID","ProjectName")
Which is still throwing an error, though a yellow sign error. The suggested fixes are
1. decrease the number of items. but these are already below 500 items
2. simplify the formula. how to do it? It looks to me that the formula is already very basic
3. Change data source location. I would really like to keep it where it is. Is this really the reason why it is breaking?
