Extraordinary happenings (to me anyway)

I am sorry if I am breaking the rules, but it would be almost impossible to include the code which is giving trouble. In a nutshell, I have defined three arrays in declarations at the start of a module. Most of the (Private) subs recognize these arrays. One sub refuses to do so. In others the variables contained in the arrays are being used correctly but when I right click on the arrays to get the "definition", I get the message "not recognized". Have I exceeded the number of arrays allowed? I temporarily changed the arrays to public although my understanding is that this is not necessary (and has never given trouble before) but this made no difference. The basic I am using is that contained in Office 2007. My problem is not to do it better, but to do it at all. I would be most grateful for any help you could give.
