进行 + something：carry out / execute / do something. something is 进行中 / something 正在进行（中）：something in progress

Maybe you should put some examples here, so we can locate where you go wrong.

I will try my best to translate it! I checked "进行" in Chinese dictionary, and it is said "进行" has 2 meanings. First one is "engage in (some kind of activities)", in Chinese "从事（某种活动）". For example: 进行讨论(have a discussion) 例句: 就相关问题进行讨论 (have a discussion on this relevant topic); 进行教育和批评 (educate and critisize) 例句: 如何对学生进行教育和批评 (How to educate and criticize the students)； 【注意】 "进行"总是用在持续性的和正式、严肃的行为，短暂性的和日常生活中的行为不用“进行”，例如不说“进行午睡”，“进行叫喊”。(Notice: "进行" is used in consecutive, formal and serious situation. We do not use "进行" in temporary action and the activities in daily life. For instance, we do not say "进行午睡-snap" or "进行叫喊-shout")。 the 2nd meaning is "go forward", in Chinese "前进"。 for example: 进行曲 (the song for parad, and the song has distinct rhythm and clear structure)。 P.S. The grammar of your question "我总是用进行错" seems not correct, it is better to say“我总是用错‘进行’这个词” or "我总是用不好‘进行’这个词"~ hope this helpful~

打个比方，i am learning english. 可以翻译成 我正在学英语，就是进行时。
