    1. CO1. My expected outcome is to "sort the data by clicking the heading of the table column." E.g. Click ID sort in numerical order of the ID column, Click Price sort in numerical order of the Price column, etc etc. 2. $$Price outputs a numerical value from the $price variable and I've added a $ in front. It works, didn't know it wasn't correct syntax. 3. Didn't know the page needed to be stated, this is the first time I've done this kind of thing and assumed it would look for the query on the current page.

    2. CO4. What checks would you suggest? 5. The two different variables are because the code at the bottom is an example I found on the net, i customised to suit my code on my site. I did mention it was sourced from an example. 6. The single quotes worked, I've had issues with mixing single with double when spitting out html data from php. 7. Will be debugging but looks like my problem was not mentioning the page in the query for a start so basically nothing was happening.

    3. CO@Bjorn 1. I'm not here to decipher your mind. Your issue is because of a certain problem. I don't know your exact problem, so I can't give you an exact solution to that problem. 2. if `$price` is 5, `$$price` returns `$5` which is probably 0 or undefined. It is also bad practice. 3. Now you know. 4. Checks that are outside the scope of your learning at the moment. Just code for fun for now. 5. It's common to make small mistakes and syntax errors, even for experienced devs. 6. What works for you is different from what works for everyone and different from W3C standards sometimes.

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.
