I don't understand this phrase. :-) Someone can help me?

I don’t understand this phrase: Als ik wat langzamer moet praten moet je het maar zeggen… :slight_smile: Someone can help me? thanks

“Als ik wat langzamer moet praten moet je het maar zeggen.”
“If I what slowlier must speak must you it but say…” (literally translated)

I understand it to mean:
If I need to speak more slowly you only need to tell me (say so).

I am new to Dutch, but I did the same lesson, so if I got it wrong just let me know :slight_smile:

Please tell me, if I need to speak more slowly.
