Robot studio isn't telling me where my syntax errors are

RAMmechie

I'm working on some code in Rapid, but RobotStudio doesn't tell where or why my code doesn't work.
I think the line below might be the problem.
checkpoint := IsReachable(point, printhead, wobj0);
I'm not sure how to fix it

Below is the rest of the code

MODULE MainModule

Hello,

I've test your code, all works fine...

I've this text on ReadTest1.txt:

[200,0,0]<br>

Can you give us your error text?

PS: When you paste code on post, use Code format (in pilcrow down list).

Funnily enough the code started working the next day. I don't know why it didn't work before
