Date Field - External URL - Visual Composer Module - DHVC Form Module -- 3

Hello, Bought this module called DHVC Form that works and it's based on Visual Composer module. [login to view URL] The DHVC Form module has a feature that allows data to be submitted to a external URL as in. http://externalurl.tld/fieldone=somenting&fieldtwo=something The DHVC module has a datefield, that ca let you choose a date. The sumbited data from this field should be dd/mm/yyyy but the result it's dd%2Fmm%2Fyyyy, because somehow the "/" - slash it's not decoded. Both modules will be provided by me with the latest version, as well as the field that are used. I want someone that - it's familiar with the Visual Composer module and can fix so the external url (past jobs) - provide me a changelog with the modifications that were made to the DHVC module, what files at what lines in a pastebin.com. Please bid only if you have prior experience and understand the requirements.
