Using sed command

Hi,
My requirement is like this:
I have a file with the following data

ABC=01-01-1900
EFG=01-01-1901
xyz=01-01-1900

I want to write a script which will replace the 01-01-1900 that correspond to the ABC to be replaced with a new date string like '06-21-2007 02:12:33'.

I tried a sed command like this sed -n 's/${SRC}/${VALUE}/gp' FILE.txt

But it is not working..
Please help me on this

Use double quotes instead of single quotes. Single quotes prevent the expansion of the variables.

Thanks Franklin..

I tried the command like this now

sed -n "s/${VALUE}/${TIME}/gp" $FILE.txt.

But it gives me an error like this now
sed: command garbled: s/01-01-1900/

Lose the single quotes they prevent expansion of the variables

sed -n "s/${SRC}/${VALUE}/gp" FILE.txt
