Transposing an entire score (fwd)

[peter . gambie]

I have a piece of choral music in 8 parts. It's too low for my choir to 
sing, so I want to transpose the entire piece up from the key of F to the 
key of A. 

I asked an almost identical question on the forum in November and the first 
answer I received worked. Unfortunately, it doesn't work this time, perhaps 
because the score is formatted differently. 

As a mere musician, I'm afraid many of the answers I received last time were 
too technical for me to understand, so I'd be really grateful for simplicity 
in responses. 

I'm enclosing the file, just in case someone wants to fix it for me. 

Thank you. 

Peter
