Well that makes sense, but it still hurts my feelings…
I have tested this on IE11 and I get the same results. I am able to resolve the problem by making sure that the column type was changed to date/time. If I leave it as general I get that problem. Not sure if this is a defect or not as it seems to be looking at the field type and if the column type doesn't match the field type it is giving that error. Just something I will need to keep my eyes opened for.
Nice project by the way. I plan on using it in a couple projects right away.
