Hello @ohassanRFYG3 
Congratulations to your first graph! We can help for sure.
To help, we need a higher resolution screenshot so we can read everything. Additionally you have to open ALL nodel results so we can see what is going on in your graph. At last we need to know what error messages you are getting. So you have to wright them down for us or make additional screenshots of the warnings.
