No problem. In fact, these fora appreciate people publishing their attempts so these can be analysed and discussed, so the learning curve for everyone becomes steeper.
Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

Not knowing anything about your input file nor the desired output, just looking onto your code, I came up with
Code:
gunzip -c "${i}" | awk '
/<Setup/        {StartTime = "      " $0
                }
/DN/            {dn        = " " $0
                }
/<Target/       {$0 = $0 ORS dn ORS StartTime
                }
1
' > /tmp/"${FILE}"

Test and come back with results.

envsubst

ENVSUBST(1)								GNU							       ENVSUBST(1)

NAME

       envsubst - substitutes environment variables in shell format strings

SYNOPSIS

       envsubst [OPTION] [SHELL-FORMAT]

DESCRIPTION

       Substitutes the values of environment variables.

   Operation mode:
       -v, --variables
	      output the variables occurring in SHELL-FORMAT

   Informative output:
       -h, --help
	      display this help and exit

       -V, --version
	      output version information and exit

       In  normal  operation  mode, standard input is copied to standard output, with references to environment variables of the form $VARIABLE or
       ${VARIABLE} being replaced with the corresponding values.  If a SHELL-FORMAT is given, only those environment variables that are referenced
       in SHELL-FORMAT are substituted; otherwise all environment variables references occurring in standard input are substituted.

       When --variables is used, standard input is ignored, and the output consists of the environment variables that are referenced in SHELL-FOR-
       MAT, one per line.
