Bash: bad substitution problem...pls help!

I have this situation in my script (simplified):

A=C
C=10

I need to get number 10 using just A variable.

I tried with :
echo $`echo $A` - but i get $C string (i need number)


Thanks very much for any help!

Code:
eval echo "\$$A"

and (bash specific):

Code:
echo "${!A}"
