It is an array element.  It can hold any number of things, but it would appear in your case to most likely be either a string or number.

A good way to know what it holds is:

[code=php:0]var_dump($_POST[$i."1"]);[/code]

the $_POST array is an array that holds all of your submitted values from your form. the stuff inside the [] points to which position in the array. the $i."1" is taking the value of $i and concactonating 1 to it.  I assume that there is a loop where $i is incremented or something, so one one of those iterations of the loop, it might actually look like $_POST[11], $_POST[21], $_POST[31], etc... those being the 12th, 22nd, and 32nd positions in the $_POST array (because arrays start at zero, not 1). 

What value the $_POST[11] (example) holds can be anything.  Look at the form you got the posted info from.  it's being inserted into your dValue column in your db so that might help you.
