Please, why that code don't run?. Thank you.

+ Code Snippet

dim a(5)
a(1)=12
a(2)=74
a(3)=63
a(4)=61
a(5)=8

erro1=5
erro2=11
erro3=13
erro4=46
erro5=41
erro6=25

for x=1 to 5
for y=1 to 6
if a(x)=74 and "erro"+str$(y)=46
print "correct"
else
print "incorrect"
endif
next y
next x
wait key

You can't make a variable name out of a string.
Since you already have an array a, why don't you just make erro an array as well?
That would solve everything

-> Oh, come on...

The reason your code does not run is because of this line:

if a(x)=74 and "erro"+str$(y)=46

You were trying to compare a string with a number.

Try this:

+ Code Snippet

dim a(5)
a(1)=12
a(2)=74
a(3)=63
a(4)=61
a(5)=8

dim erro(6)
erro(1)=5
erro(2)=11
erro(3)=13
erro(4)=46
erro(5)=41
erro(6)=25

for x=1 to 5
for y=1 to 6
if a(x)=74 and erro(y)+y=46
print "correct"
else
print "incorrect"
endif
next y
next x
wait key
