In order to determine what exceptions are causing the red triangle in your review screen of Importacular, you will need to open your control report and go to the Exceptions tab. There will be a column on that tab that will detail why this record did not validate/import.
You will find your control report in the location you selected prior to the review screen and with the name that you determined. In the example below, we selected the Users drive and named our file "Control."
When you open your control report, you should see three tabs at the bottom (if you do not, make sure that your control report was not incorrectly changed to a .csv rather than the .xlsx it defaults to).
Open the tab for the Exceptions and locate the column with the list of Exceptions. If you do not understand what they mean, we recommend that you begin by searching our Knowledgebase. Below you can see a sample of this section of a control report.
