Help with manipulate and 3D plotting

Good afternoon,

I could really do with some help with this.

I have an array containing a series of x, y pairs, and I have a
formula which takes these x, y pairs as inputs along with three other
variables a, b, & c to calculate each z value.

What I need to be able to do is calculate the corresponding z value
for each x, y pair, then create an interpolated surface through these
x, y, z points. Three slider bars will then update the values of a, b,
and c which in turn update the z calculation and update the plot.

The stage I am currently at is as follows:

Manipulate [ ListPoint3d [ Table [ functionName [x, y, a, b, c], {x,
10, 40}, {y, 10, 90} ], ColorFunction -> "Rainbow" ], {a, 0, 1}, {b,
0, 1}, {c, 0, 1} ]


With the above example I am not using the correct input matrix
containing x, & y just to try and get it working, but the slider bars
are unresponsive and it also doesn't look like the values are being
calculated correctly either.

Any feedback/advice would be greatly appreciated,
Many thanks,
EC
