You overwrite the PATH in the inner loop. After the first iteration of the outer loop the PATH does not contain the common locations that the shell needs to find any binaries.
Do yourself a favor and do not mess with the PATH. Certainly, it is not necessarily to change it in every iteration of the second loop. Most of the times, when the need arises, is to "add" to the PATH, but it is uncommon to completely overwrite it.
In those, cases, you use the following statement:

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.
As an example I've written a script called question (The fist command is to show what is the contents of the... (2 Replies)

gsettings help [COMMAND]
DESCRIPTION
gsettings offers a simple commandline interface to GSettings. It lets you get, set or monitor an individual key for changes.
The SCHEMA and KEY arguments are required for most commands to specify the schema id and the name of the key to operate on. The schema id
may optionally have a :PATH suffix. Specifying the path is only needed if the schema does not have a fixed path.
When setting a key, you also need specify a VALUE The format for the value is that of a serialized GVariant, so e.g. a string must include
explicit quotes: "'foo'". This format is also used when printing out values.
COMMANDS
get
Gets the value of KEY. The value is printed out as a serialised GVariant.
monitor
Monitors KEY for changes and prints the changed values. If no KEY is specified, all keys in the schema are monitored. Monitoring will
continue until the process is terminated.
writable
Finds out whether KEY is writable.
range
Queries the range of valid values for KEY.
set
Sets the value of KEY to VALUE. The value is specified as a serialised GVariant.
reset
Resets KEY to its default value.
reset-recursively
Reset all keys under the given SCHEMA.
list-schemas
Lists the installed, non-relocatable schemas. See list-relocatable-schemas if you are interested in relocatable schemas.
list-relocatable-schemas
Lists the installed, relocatable schemas. See list-schemas if you are interested in non-relocatable schemas.
list-keys
Lists the keys in SCHEMA.
list-children
Lists the children of SCHEMA.
list-recursively
Lists keys and values, recursively. If no SCHEMA is given, list keys in all schemas.
help
Prints help and exits.
