I do not observe, no problem is your token, I would like to deploy it, if you could send me these import files
or can I send you the other files?
yes, I can send them I would like to try to display it, to know why the error occurs
I was asking how I can send you the other documents, do you have an email I will do a Wetransfer
you can upload everything to github and share the repository
I don't use github for the moment I work on remix.ethereum
