求助翻译！！

我用skype跟老外聊天，但其实我的英语很一般，只能够是应付日常的沟通！而且他们在聊天的时候，都没有标点符号！！ 请各位帮帮忙，帮我翻译一下！感谢！ yes the issiuse was forst purchase was good but the second ended up being the plastic heat seal and not the threaded seems. i would like to skyoe to insure we are both on the same page as for as what we want to purchase. 我知道以上是有个别单词是对方打错了的。我主要是不明白从but 后面的那段！
