Trying to take file numbers from a file, pass them to sed to change strings in corresponding lines
I have a bunch of file numbers in the file 'test':

I'm trying the above command to change all the instances of "H" to "Na+" in the file testsds.pdb at the line numbers indicated in the file 'test'. I've tried the following and various similar alternatives but nothing is working:

Code:
cat test | while read line; do line=$line"s"; sed -i "$line/H  /Na+/" testsds.pdb >> well ; done

Any help would be greatly appreciated.

BWILD(8)						     Network backup, utilities							  BWILD(8)

NAME

	bwild - Bacula's 'wildcard' engine

SYNOPSIS

       bwild [options] -f <data-file>

DESCRIPTION

       This manual page documents briefly the bwild command.
       This is a simple program that will allow you to test wild-card expressions against a file of data.

OPTIONS

       A summary of options is included below.

       -?     Show version and usage of program.

       -d nn  Set debug level to nn.

       -dt    Print timestamp in debug output

       -f <data-file>
	      The  data-file  is  a  filename that contains lines of data to be matched (or not) against one or more patterns. When the program is
	      run, it will prompt you for a wild-card pattern, then apply it one line at a time against the data  in  the  file.  Each	line  that
	      matches will be printed preceded by its line number. You will then be prompted again for another pattern.
	      Enter  an  empty line for a pattern to terminate the program. You can print only lines that do not match by using the -n option, and
	      you can suppress printing of line numbers with the -l option.

       -n     Print lines that do not match

       -l     Suppress lines numbers.

       -i     use case insensitive match.
