sed - Add a variable line to the end of a block beginning with a regex

Hi,

Need some help with sed.

I have a file that has sections :

e.g.
Code:
[section]
a=blah
b=blah
 
[section2]
d=blah
e=blah


There's many sections in the file.

I have a variable $line which contains a new line.
I have another variable $section with the section.
There may be sapces in the $line

I need to append line $line to section $section.

I tried this but I got a Label too long error :

Code:
section="section"
line="blah = blah"
sed -e '/\['$section'\]/{:a;n;/^$/!ba;i\'"$line"'' -e '}' testFile
