no radius for atom 17 atomic number 30



Hello all,
 I am having some trouble getting gaussian 98 to read in a
 van der Waals radius for Zn.  The radius I found is 1.39
 angstroms.  So I use the pop=(chelpg, readrad) command
 and place the line Zn 1.39 at the bottom of the variable
 section.  My input is shown below:
 #P HF/STO-3G SCF(Maxcycle=500) pop=(chelpg, readrad)
 density=current Opt
 HF/STO-3G//HF/STO-3G

 Does anyone know if I using the proper syntax?  I did a
 little searching on the web and found a message that
 mentioned that I should do it this way.  But I get the
 error message:
