    1. COHi Jaya Many thanks for the response, I have changed my code to generate the string using your methods, it is a much neater way than the way i was doing it, however i am still receiving the same error. HTTP Error 500 Internal server error. my customer whom i am posting sale details to can see my string but they are complaining that i am submitting everything as a string it should all be parameters of which the last parameter contains a Json string? any idea what this means?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
