If you copied and pasted numbers from your 1098 documents, some of those numbers are hyperlinks. If you go back through the section and manually re-enter them that should eliminate your issues (do not try to fix if from the frame under the error message).
Also, make sure there are no '0's listed. If the box is blank, leave it blank.
If that does not work, sometimes the only way to solve this problem is to delete your 1098-T and re-enter the information again, manually (do not copy and paste).
