javascript - Mysterious "undefined is not a function" -

I am pulling my hair to try to solve this error, it creates an uncheck type error Is doing: there is no undefined function :

  trange [abs] [i] = benton (E1, z1, pa1, pI_pot, pz2, PA2);  

Here's my job:

  Function Benton (e1f, z1f, a1f, I_potf, z2f, a2f) {// My content BENTON_return = (( A1f / tu) / (z1f * z1f) * (pringlow [q] + bzz * cz [n]); Return BENTON_return; }  

It is, who has not shed any light on this issue. I know that the question has been asked before the variation, but I hope the general example of this error will be some use for other people who are learning JS. Any input would be appreciated.

update

In the interest of clarity, here are some codes which hopefully will put this problem in better context:

  Function Dreamweaver () {"strict use"; ... transform = new array (1); For (i = 0; i & lt; trange.length; i = i + 1) {trange [i] = new array (MAXE); // Create a new 2-D array} ... i = 0; Do {e1 = tenerg [i]; Trans [AB] [I] = Benton (E1, G1, P1, PI_pot, PG2, PA2); I = i + 1; } While (tenerg [i] <8.0); ...} function bentone (e1f, z1f, a1f, i_potf, z2f, a2f) {"rigorous experiment"; ... // many more math bzz = (31.8 + 3.86 * Math.x ((5.0 / 8.0) * logi) * (A2F / G2F) * 1.0 E-06 * Math Ext. ((8.0 / 3.0) * Math.log (z1f)); BENTON_return = ((a1f / TAU) / (z1f * z1f)) * (pringlow [q] + bzz * cz [n]); returning BENTON_return;}  < / Pre> 
 JSLint responds with the complaint that  'benton' was used before it was defined . I successfully did this type of job successfully, where I had a substrate I created the equivalent of JS here. I wish to implement which return a single value. I know that this is probably a small error, but I do not think what I'm doing is wrong. Any feedback will be great. 
 

I have procedures to solve these issues, which are the functions array of single values Pass which is overwritten for each subsequent call, then the call comes from:

< Pre> trange [i] = benton (e1, z1, pa1, pI_pot, pz2, pa2);

... from ...

  BENTON (e1, z1, pa1, pI_pot, pz2, pa2, reichweite); [I] = Rivet [0];  

My job is:

  function BENTON (e1f, z1f, a1f, I_potf, z2f, a2f) {// My content benton = ((A1f / TAU) / (z1f * z1f)) * (pringle [q] + bzz * cz [n]); Benton return; }  

... from ...

  function BENTON (e1f, z1f, a1f, I_potf, z2f, a2f, reichweite) {// my Luggage review [0] = ((a1f / TAU) / (z1f * z1f)) * (Prangelo [q] + bzz * cz [n]); Return rivet; }  

On the other hand, for processes that behave like sub-rooten , I have a multi-valuable array [] Pass which is actively populated and has not been overwritten.

Hope this will help those new JSs
