Hi Cindy,
Thank you for your post.
You can continue using your InfoPath forms by installing Qdabra's FormsViewer app from the SharePoint app store.
We've helped countless customers move form investments to O365 with minimal effort.
Lots of cool new techniques and a FormsDesigner coming soon. All for at least two orders of magnitude less cost than alternatives.
Check out the FormsViewer v5.2 training content underneath Downloads on this site. Lots of freebies.
Let us know if you want free help.
Cheers,
Patrick
