Hi John! Thanks for the reply. Answering to your question… The problem was not on the creation of the form. It was correctly created and I was able to work with it for a while until its reference was not found any more. But I already found the problem… While working in the form (applying controls, formatting them, renaming them, etc…). I accidentally renamed the form instead of the control I wanted to rename… And of course the reference to its previous name was lost… And I started everything with a new form and it happened again and so on… For three or four times before I posted this message… What are the odds of a thing like that happen?
