Can someone > please explain why this doesn't work. $test is a string variable, not an array. To add elements to an array, either use $varname[], array_push(), or array_unshift(). BTW, when an error message says that a variable is not the right type, this is a good time to use gettype() and/or var_dump() in order to check that the variable really has the type and value(s) what that you expect. -- CC
