Cut not working in a loop

I have a function "MyPrint" that runs great on a file (BaseData.txt) that has one line of data. If i add rows to the text file it's reading the tFile variable becomes a list of every field 2 in the file. To correct this, i tried to call the function from a loop where i read one line at a time and pass the line to the function. >>>The problem is when i try to cut the variable containing the $line0 I get an error cannot open...then it gives the proper value the first field in the line i'm trying to cut. It repeats this cannot open line for each column in the $line0 printing proper values.

I've seen other posts like this but none of the solutions have worked for me. Completely at a loss for new ideas desperate for help!

BaseData.txt has 2 rows:
hsun test1a.sas7bdat 8269135872 7.70123
hsun test1a2.sas7bdat 8269135872 7.70123

Code:

 
#!/usr/bin/ksh
 
function FindPath3 {
 find /u03/hsun -name ${1} 
}
function MyPrint {   
tfile=`cut -f2 -d ' ' ${1}`
#tfile= `echo ${1} |cut -f2 -d ' '`
echo $tfile
print `cut -f1,2,3,4 -d ' ' ${1}`, `FindPath3 ${tfile}` > /home/kemard/Test3_OP.txt
} 
 
#MyPrint /u03/kemard/BaseData.txt 
 
  while read line0
     do 
     #MyPrint ${line0}
     lineValue1=${line0}
     lineValue2=`cut -f2 -d ' ' ${line0}`
     echo "line value 1 is: ${lineValue1}"
     echo "line value 2 is: `cut -f2 -d ' ' ${lineValue1}` "
     #echo "line value 2 is: ${lineValue2}"
     #cut -f1,2,3,4 -d ' ' ${line0} > /home/kemard/Test3_OP.txt
 done < /u03/kemard/BaseData.txt

cut

CUT(1)							    BSD General Commands Manual 						    CUT(1)

NAME

     cut -- select portions of each line of a file

SYNOPSIS

     cut -b list [-n] [file ...]
     cut -c list [file ...]
     cut -f list [-d delim] [-s] [file ...]

DESCRIPTION

     The cut utility selects portions of each line (as specified by list) from each file and writes them to the standard output.  If the file
     argument is a single dash ('-') or no file arguments were specified, lines are read from the standard input.  The items specified by list can
     be in terms of column position or in terms of fields delimited by a special character.  Column numbering starts from 1.

     list is a comma or whitespace separated set of increasing numbers and/or number ranges.  Number ranges consist of a number, a dash (-), and a
     second number and select the fields or columns from the first number to the second, inclusive.  Numbers or number ranges may be preceded by a
     dash, which selects all fields or columns from 1 to the first number.  Numbers or number ranges may be followed by a dash, which selects all
     fields or columns from the last number to the end of the line.  Numbers and number ranges may be repeated, overlapping, and in any order.	It
     is not an error to select fields or columns not present in the input line.

     The options are as follows:

     -b list	 The list specifies byte positions.

     -c list	 The list specifies character positions.

     -d string	 Use the first character of string as the field delimiter character.  The default is the <TAB> character.

     -f list	 The list specifies fields, separated by the field delimiter character.  The selected fields are output, separated by the field
		 delimiter character.

     -n 	 Do not split multi-byte characters.

     -s 	 Suppresses lines with no field delimiter characters.  Unless specified, lines with no delimiters are passed through unmodified.

EXIT STATUS

     cut exits 0 on success, 1 if an error occurred.

SEE ALSO

     paste(1)

STANDARDS

     The cut utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
