MapScript queryByPoint index error

[Jerod Clabaugh]

All:

I am in the process of using PHP/MapScript to build a dynamic point
layer that I can query.

When I query the point layer, the result (using an echo) shows me

        $result ->shapeindex=-1

The code to query the layer and to build this layer are detailed
below. I have built a rectangular query, which works with the same
dynamic layer, but I am having trouble with the point layer.

Any advice on why I am getting the wrong indexes in the results of
queryByPoint on the dynamic layer?


Thanks in advance,
