when you define a variable, you must not write a '$' in front of it. the 
above line should read:

dynipadd="`ifconfig ppp0|grep 'inet addr'|awk '{print$2}'|sed -e '/.*://'`"

if ur networkdevice is ppp0 this should work (u shld add the path to 
ifconfig, i didn't in order to sqeeze it in a line :-)
