Hi,
So I have two tasks: 'a' and 'b', each with 4 blocks.
I have counterbalanced the order of the 4 blocks within each of the two scripts as follows:

<expt >
/ subjects = (1 of 8)
/ groupassignment = groupnumber
/ blocks = [1 = training_1_gender; 2 = training_1_emotion; 3 = training_1_both; 4 = block_1; 5 = block_2;
6 = training_2_gender; 7 = training_2_emotion; 8 = training_2_both; 9 = block_3; 10 = block_4;]
</expt>
....

I am wondering how the group number assignment will work if I combine the two scripts using batch element, and then counterbalance the order of task 'a' and 'b' in that script. Will it ask for group number three times - one for a vs b script, one for a script, and one for b script? I do not want the within script counterbalancing of the blocks to be affected by the new script.

Thanks for the help, I think I am just confusing myself.

No, it won't ask for group number three times. The groupnumber provided when you run the batch script is the one that filters down to the task scripts.

So what is the best way to do this double counterbalancing? I do not want the two to impact each other.

Do I need to write out each possible combination in a script that codes for both 'a' and 'b'?

1234 (a) + 1234 (b)
1234 (a) + 2341 (b)
1234 (a) + 3412 (b)
....

Is there a faster way to do this? Seeing as this way would result in coding many many possible experiment orders?
