call a sh script from within an existing script

I have an external monitor (sh script) that runs a program that calls a another sh script to run and then looks for the results.

 

 

It work fine from the cli but not when I configure it as an external monitor. Is there something I need to do to have the LTM allowed to run the external script?

 

 

I verified with tcpdump that the external monitor (sh script) only works when I remove the option/portion that calls on the additional script to run.

 

 

any help is REALLY appreciated.
