how to remember parameter values used on last build in Jenkins/Hudson

how to remember parameter values used on last build in Jenkins/Hudson

I need remember the last parameters values when I begin a new build with
parameters.
I Have two string parameters
${BRANCH}
${ServerSpecified}
On The first build execution I need those values in blank, but for the
second execution i need the values of the first execution, in the third
execution the values of the second execution, and so on...
I need install a plugin?, I tried using dynamic param with groovy, but I
can't extract the last value, Somebody know how make this or other best
idea.. thank you guys
