Opening a form as a Site Member gives: "Sorry, you don't have access to this page"

Symptom: 
You have a SharePoint list and the user reporting the issue is a Site Member. When the user tries to open a list item in view mode they are redirected to a page with the message: "Sorry, you don't have access to this page"

Issue: 
The issue I had was that one of the fields in the list was a person field. This field restricted the choice of people to a SharePoint Group. On checking this SharePoint security group. I found that the setting for this group "Who can view the membership of the group" was set to "Group Members".

Resolution:
Once I changed the "Who can view the membership of the group" to "Everyone" everything worked as expected.

Nintex Forms: Birthday Date Picker Year

Issue: By default the date picker will display the years as ±10 years. This is not suitable for a Date of Birth date picker. 

Fix:

1. Edit the form in Nintex Forms.
2. Double click the Date picker field.
3. Open up the "Advanced" section.
4. For setting "Store Client ID in JavaScript variable" change to "Yes".
5. An additional field will be visible called "Client ID JavaScript variable name". Provide it a name. In my example it's called "birthdayControl".
6. Click Save. Dialog will close.
7. Click "NINTEX FORMS" on the ribbon.
8. Click "Settings"
9. Open up the "Custom JavaScript" section of the "Settings - Form" dialog.
10. Add the following:
    NWF$(document).ready(function(){
          NWF$('#'+birthdayControl).datepicker('option',{yearRange:'-80:-0'});
    });
    
11. Change the variables to suit your situation:
1. birthdayControl: Client ID Variable set in step 5 above.
2. -80: How many years back you want to display in the date picker.
3. -0:How many years forward you want to display in the date picker.
12. Click "Save". Dialog will close.
13. Publish the form.
14. Your specific date control should now show a more appropriate year selection for Date of Birth.
