You need to evaluate the "name" variable before you can use it that way,
essentially give the shell a chance to process it as though it was typed in.
eval cd $name
Depending on how much you are doing with name, it might be useful to do this first to avoid a lot of "eval"s.
eval name="$name"
As you are changing directory, be sure that you go back to a known place between "cd" commands
or it may not find the directory that you are looking for.

eval
eval(1T) Tcl Built-In Commands eval(1T)__________________________________________________________________________________________________________________________________________________NAME
eval - Evaluate a Tcl script
SYNOPSIS
eval arg ?arg ...?
_________________________________________________________________DESCRIPTION
Eval takes one or more arguments, which together comprise a Tcl script containing one or more commands. Eval concatenates all its argu-
ments in the same fashion as the concat command, passes the concatenated string to the Tcl interpreter recursively, and returns the result
of that evaluation (or any error generated by it). Note that the list command quotes sequences of words in such a way that they are not
further expanded by the eval command.
EXAMPLE
This procedure acts in a way that is analogous to the lappend command, except it inserts the argument values at the start of the list in
the variable:
proc lprepend {varName args} {
upvar 1 $varName var
# Ensure that the variable exists and contains a list
lappend var
# Now we insert all the arguments in one go
set var [eval [list linsert $var 0] $args]
}
