Hum, the code you posted on this forum is not in -- not even close to -- 
Mathematica syntax, so one may wonder if you even try to write anything 
by yourself...

To help you started, the erf function is *Erf[z]* in Mathematica and it 
works over the complex field.

     In[1]:= Erf[1.5 - I]

     Out[1]= 1.0784+ 0.0279637 I

Also, in addition to the introductory material available with any 
standard installation of Mathematica, you should read the following 
short articles:

"How are the different brackets, such as {}, [], and () used in 
Mathematica?"
http://support.wolfram.com/mathematica/kernel/features/brackets.html

"Why doesn't sin[x] work in Mathematica?"
http://support.wolfram.com/mathematica/kernel/features/casesensitive.html

"What is the difference between =, ==, === in Mathematica?"

"Why aren't my assignments and function definitions working?"
