defect description:-on clicking the start button after entering the values it is again showing a popup to enter the values and not going any further
steps to reproduce:-Molecular Fluorescence Spectroscopy ->Experiments ->Familiarization with Excitation and Emission Spectra, Mirror Image Relation and Stokes Shift ->Simulator->Click here to go to lab
expected result:- i must be able to proceed further so that i could have completed my experiment
actual result:- it was showing a popup on clicking the start button as mentioned in the experiment to click the start button inspite of going any further
