Iterate array using loop over ssh

A simple script:

Code:
#!/bin/bash
test=test
test1=(test1 test2 test3)
echo ${test1[*]}
ssh server 'echo '$test'; echo '${test1[*]}' ; echo '${test1[1]}' ; for m in $(seq 1 $(echo '${test1[*]}' | tr " " "\n" | wc -l)); do echo $m ; echo '${test1[$m]}'; done'

Here is the result:

Code:
test1 test2 test3
testing
test
test1 test2 test3
test2
1
test1
2
test1 ***this should be "test2"
3
test1 ***this should be "test3"

Why is it not being iterated as expected?

I read somewhere that ssh doesn't know about the variables, etc etc. Then why can I see that "echo ${test1[*]}" iterates correctly?

BUMMER Smilie I really need this Smilie

Can you guys help me out?

**EDIT: Forgot the CODE tags, sorry Smilie
