Looks like you did a copy/paste from a diff form and the columns did not line up correctly. They changed the order a bit ago so old forms will not paste in correctly. Like you have field-list for read only which is not valid (just yes/no).
Also it is complaining on links. This means you used Ctl-C V which makes a link to the original sheet. You always want to right click Paste Values in 123. All your drops downs are messed up now too.
I suggest you start with a new survey and go column by column and use Paste values to clean it all up.
Hope that helps
