help: how to edit convert leap page in sugar 6

[smoothumut]

hi everyone,
could you please tell us how to edit convert lead page in sugar 6. i tried to edit getwideformbody function in different modules, but the convert lead page stayed the same, nothing changed. I know, some of you posted the same answers many times regarding this issue but i couldnt make it. i even deleted those <module>formbase php' s still the same. i couldnt find convertlead.php file either. should i make changes in view.convertlead.php. ? could you please help on this issue? i basically try to remove some fields in contacts section of convert lead and add some fields to accounts. i am not expert in php's so can you please be specific regarding codes.
please help..
thanks everybody..

Sugarcrm 6 is still in development ... if you are seeking to use sugar for production purposes you should use 5.5.x.

thanks for the reply Salesagility. you are right. i made a small search and saw that i cant upgrade beta versions to GA's.( if i am wrong please notify me. ) then i decided to customize sugar 5.5 for my startup business. thanks to you i turned out from a big mistake.
have a good work to all
