Gwen Posted February 9, 2005 Share Posted February 9, 2005 Hello. I have four fields: -A ("total") -B ("correct") -C ("incorrect") -D ("blank") I want to validate fields B-D (always, no over-ride on data entry). I've asked for an error message to displayed any time the validation fails (i.e., B ~= A-C-D). I have two problems. First, the validation doesn't always work. How can I trouble-shoot this? And is there a way to "trigger" the validation for a field with data that were entered before the validation was set up? Second, I would like to validate field D, but it should not be flagged as invalid if the result (D=A-B-V) is 0, since 0 is a possible value. Thanks in advance. gwen Link to comment Share on other sites More sharing options...
