Hi everybody,

In my blog post I used the word 'triple' which as I understood is not a word. What I want to say is:
'I want to discuss a problem which often 'trips' newbies and even professionals'. In other words, the problem many people can make an easy mistake.

I'm thinking of a word stumble or trip, but I am not sure this word 'trips' can be used in this context, e.g. the problem that trips.
Someone who pointed out my incorrect usage thought I should have used 'troubles'. I think I can use this word, but this is not exactly what I wanted to convey.

What can you suggest?

Thanks in advance.
