jmeter - Login post request does not work -

i had @ similar questions here, did not find dynamic parameter, session information etc need around using regular expression extractor login post request. network traffic on chrome seems same. jmeter seems pass required parameters , and have http cookie manager set (as depicted in snapshot).

here jmx script. have struggled seemingly simple use case 1 day have been clueless far.

i see dynamic parameters.

to make work,

1. send simple http request www.zalando.de/login

<input type="hidden" name="_sourcepage" value="wwscwmvvyn3usajdv0vmruaxy8np_kj8xwbkjpam6z4zbx3a1i4qrat340npsm8wopoclw1uvy0=" /><input type="hidden" name="_xtk" value="a2tpizqszqyptrudhhtxoxhmbjsyjpgwchzlfzyz41iffo4udosyo0cyir7gls6m" /><input type="hidden" name="__fp" value="47scl-scdbc=" />

2. from http response, extract __fp, _sourcepage, _xtk
3. send login request updating these values in thr http request.

it should work now.
