Try this:

TEMP_SIZE=$(eval echo \$${INST}_tit_for_tat_SIZE)

Sorry don't have shell at this time to test.

There appears to be another problem.  The variable name hum-tum is invalid.  Dash is an invalid character in the variable name

The fix is to use alphanumeric  characters and underscores in variable names.
