runtime error divide by 0

[Snosnosnow@xxxxxxx]

  I am using TS2k as the platform.
 
  When I use a standard cci on the tick ( price goes + and - )
  it works fine.
 
  When I use the jurik ccx it will give me a runtime error. Attempted
  to divide by zero.... . I noticed that the function has jrc.ccx.2k =
iff
  (md > .00001, diff / MD, 0 ) which is the suggested code.

I have tried .00000000001 and 1.  Both still give me errors on the tick.

Function is below.
 
  The ccx is faster than a cci smoothed with the jma.
 
  Can you suggest how to recode this so I do not get the runtime error.

Please email me direct and the group, I am on the digest.
 
  Thanks
  Sno

============================================================

Function:  JRC.CCX

Purpose:   similar to classic CCI except that the input series 
           is first smoothed by JMA

Note:      Input parameter LENGTH should be greater than 8.0

Note:      Lookback will be 3 TIMES the size of LENGTH

inputs : length(numericsimple);
vars : diff(0), available.bars(0), MD(0), k(0), maxDepth(ceiling(3*length));

diff = JRC.JMA.2k( H+L+C, 4, 0 ) - JRC.JMA.2k( H+L+C, length, 0 ) ;
available.bars = iff( currentbar < maxDepth, currentbar, maxDepth ) ;

MD = 0 ;
for k = 0 to available.bars-1 begin
    MD = MD + absvalue ( diff[k] ) ;
    end ;

MD = MD * 0.015 / available.bars ;
JRC.CCX.2k = iff ( MD > 0.0000000001, diff / MD, 0 ) ;
