I developed a custom electrical service jobs database in 2000. I can use it on XP Vista & Windows 7 (32 & 64 bit), however, when I install it on a Windows 8 (64bit) machine, it works perfectly EXCEPT when completing a job, the cost of parts & labour will not calculate only blank field. Has anyone ever had this issue ?? I have searched & searched for an answer to this. I know it won't be black & white, but any help would be very much appreciated. Thanking you in advance.
