Would have been useful if PHP had displayed a proper error! Just figured this out on Wednesday- I was trying to use LIMIT, not realising that it wasn’t compatible with MSSQL.

You then use your server-side script to multiply the page number you want to display by the range. The range is then subtracted from the result of the multiplication, leaving you with the value needed for the inner TOP. For example, if you want to view page 3 and you have set it to display 10 items at the time then you would calculate 3 * 10 - 10 = 20. Keeping in mind that the outer TOP defines the range you now have both all values needed to run the query. You would set the next/previous page links up so that they pass the page number via GET.
