Norm.Dist not working

Hi everyone,

I'm attaching over a sheet. I'm trying to build a distribution curve using Norm.Dist formula which also uses the Average and Standard Deviation.
Everytime I plot it, I'm not getting a normal distribution. Can someone please help me with this formula?

Also, is there a way to link the chart selection data to the slicer that I have created which ties to the data?

Please let me know!

Thanks
