I have come to a point well beyond my understanding of coding and mathematical ability regarding Bezier curves and applying the code to ascertain the required results.
I am looking for assistance with this particular issue.

The example file (Mystery solved! The secret of Excel curved line interpolation | The official Splitwise blog) is in excel but Im looking to add the VBA code into access and somehow manipulate the results onto a form.

This is probably a poor explanation but am I asking to much? Is it possible? Is anyone able to assist me with this problem?
