Dave,
After I sent this message I did some checking if I just created a brand new form nothing on it then I was able to get it to work. You are right that it has to do with the DataEnvironment. Once I removed it then it worked. Now the only prolbem is to get the screen to stay up long enough for the people to key some info into it.

Thanks Jim.

>If you did a SaveAsClass for a form, you lost the DataEnvironment in the process and now you probably have controls that are trying to bind to their data sources and they can't. The error should be giving you the row number of the record in the vcx that is having the problem. You can USE the vcx and look in the Properties memo of that record to see which control it is.

>>I have saved a form as a class. I have then opened a new class based off that saved form. I have added 4 items to it. Two combo boxes and 2 text boxes and an exit button. This is just a logon screen that the people will pick the company and the user to set the level of security. I have tried to run this only from the command box but it still does not wok.
