syntax error at medias_2.vhd(31) near text "in"; expecting "(",

Theres probably a ( missing near line 31.

Also, your problem in your other post is probably because you included std_logic_arith - please delete this library.

But where in line 31 i put this "("?

I've also tried to delete std_logic_arith that was defined in other part of the code, still don't work.

I dont know, as line 31 in the code you posted is a blank line.

This is a pretty simple error to find and fix yourself. Just get a decent text editor - they all do bracket matching to ensure each ( has a corresponding )

And again - I cant see your real code, so no idea whether removing std_logic_arith is going to help (but you shouldnt use it anyway)

Line 31 is the one where "for x in 1 to 48" appears for the first time.

Instead of posting fairly useless information, why not post the real code?

Or even better - fix this syntax error yourself. You know what the error is - theres a bracket missing. Why not try looking in the lines above?

It's because i don't know how to fix it. It doensn't make sense for me a bracket missing anywhere.

Without the code - I dont know what you expect us to do..
