php dynamic graph array with equation

Hi All,

This post is sort of a follow-up to a previous post, and sort of a new post; so I posted it new.

I have php coding to allow an image of a graph to be published dynamically. I am have trouble figuring the structure of the 'array/for' language.

The address is http://www.improveworkplaceefficiency.com/diab/. Just hit the Select Button as all of the pertinent choices are pre-selected.

The graph is based on a long, algebraic function for a bell curve for x = range of 0 to 150.

The answer.php page has a lot of debugging equations and coding. In the answer.php page, I ran equations for x = 0 and x = 75 and they both were good so I suspect the math and its coding are good. The address for the answer.php coding is http://www.improveworkplaceefficiency.com/diab/answer.php.txt.

The coding for the array function is in the bs6.php file at line 21. The address for the bs6.php coding is http://www.improveworkplaceefficiency.com/diab/phplot/bs6.php.txt.

Thank you All.

P.S. Can anyone recommend a good php forum? This might not be the correct forum for this question but I trust this site.
