Array inside sed

Hi guys

Let me at first describe the whole thing that I'm trying to do. Lets say I have 100 files like the following one.
HTML Code:

I want to merge all the 100 files. The second field of the 1st,3rd..so on lines shows the atom number i.e 1230,1231. All the files are numbered from 1230..1239. So for the 1st file this numbers are ok, for the second file numbering should start from 1240,1241..and this should go on all the way through the last file. I did merge the files through a loop, The way I was trying to get those atom numbers in an array, replace those array elements with a counter. My thinking was this-

Code:
 myarr=($(awk 'NR % 2 ==1' TestMe | awk '{print $2}'))
echo ${myarr[@]} 
counter=1230; 
for i in "${myarr[@]}" 
do sed "s/$i/$j/g" TestMe;
counter=$(($counter+1)); 
done

I just don't know how to replace array elements in a sed command. Or is it the right way to loop through array elements. And whenever I tried to use that piece of code it said-
Code:
-bash: syntax error near unexpected token `counter=$(($counter+1))'

Thanks a lot!

wml::std::box(3)						     EN Tools							  wml::std::box(3)

NAME
wml::std::box - Easily Create Rectangular Box SYNOPSIS
#use wml::std::box <box [attributes]> ... </box> DESCRIPTION
The "<box>" container tag puts its body into a nice rectangular box which itself is build via a HTML "<table>" construct. ATTRIBUTES
"header" This attribute switches between two totally different box variants. When it is present, a headlined box is created by the use of one single table but with space GIFs. When this attribute is missing a standard box is created by the use of two nested tables but without any space GIFs. "bgcolor" This sets the background color of the box. "fgcolor" This sets the foreground (text) color of the box. "bdcolor" This sets the color for the border of the box. The effect of this attribute is the automatic generation of a nested table construct to achieve the optical effect. "bdspace" This sets the space between the border and the body of the box in pixels. Default is 4 pixel. "bdwidth" This sets the border width in pixels. Default is 1 pixel. "width" This sets the total table width in pixels. Default is no specific width for the standard box and 300 pixels for the headlined box (because the headlined variant needs to know a fixed size to create the GIFs accordingly). "summary" Add a description of this table. This attribute is recommended in HTML 4.0. EXAMPLE
<box bdcolor="#000000" bdwidth=1 bdspace=10 bgcolor="#ffffff" fgcolor="#000000"> Foo Bar Quux </box> <box header="Foo Bar Quux Header" bdcolor="#000000" bdwidth=1 bdspace=10 bgcolor="#ffffff" fgcolor="#000000"> Foo Bar Quux </box> AUTHOR
