Very simple Verilog code, but not working on DE2

I am running this simple code, pushing KEY[3] works fine (decrement), but when I push KEY[1] the 7-seg changes with both pushing and releasing and display some random number on the 7-seg. hex_7...

First, thanks. You are right. It works now.

However, I thought that

always @ (negedge KEY[3] or negedge KEY[1] )

if (KEY[1] == 0)

is similar to

always @ (posedge clock or negedge RST)

if (RST == 0)

which works fine

I guess I was wrong ...

Thanks again
