Power Export command variable exporting problem

I have a txt file from which i am assiging a value to a variable
using the code in script1
script1.sh
Code:
export f=$(sed -n "/Freq *=/ s/.*= *//p" ${R_path}/output.txt)
echo "$f"   --------> this works

in script2 ( which executes the script1)

Code:
eval ./script1.sh

if [ "$?" = "0" ] && [ -f "${R_path}/output.txt" ]; then
echo "-------------------------------"
echo " Optimal freq  Calculated succesfully "
else 
echo " error in executing  "
exit
fi 
echo "$f"          ---------> This echo dosent work its just gives me a blank

ECHO(1) 						    BSD General Commands Manual 						   ECHO(1)

NAME
echo -- write arguments to the standard output SYNOPSIS
echo [-n] [string ...] DESCRIPTION
The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline (' ') character, to the standard output. The following option is available: -n Do not print the trailing newline character. This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2 compatible systems. Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup- press the newline character. Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does not accept the -n option. Consult the builtin(1) manual page. EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs. SEE ALSO
builtin(1), csh(1), printf(1), sh(1) STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002. BSD
