Interpolates single lines and cross table

Sample Input:
interpolation(0;5;4;125;150;137,360;0,55;0,48;1,69;1,45;3
Sample Output:
1,360


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

Works good for cross interpolation in tables and linear interpolation.

Needed a interpolation function that could make a cross interpolation because in my line of work we work with linear and cross table interpolation, could only find other types of interpolation so created this function.
