When entering IN-A and IN-B we have been having the following errors "The Field: UDF1 was not found.  You may include only active fields in an expression to be compiled at runtime."   and it increments up from UDF1 to 2 to 3 to 4. (four different error screens)   We have been just clicking "ok" to each of them to get to IN-A.  
 
Has anyone else had this and is there something that can be done to stop them?  I believe we have had this problem for quite awhile now, through several versions.  
 
Thanks,
 
We updated to 2013.4  (build 01/02/14 7:R6, Pervasive version 9.50) about a month ago.
