Empty <option></option>

Dear TBS Support,

I have error when my <option> block is empty
and return error message..
TinyButStrong Error (MergeBlock [lstgrp]): Unsupported variable type : 'NULL'.
how do I handle this empty array?

Thanks,

Just add the following line before the MergeBlock:

Thanks a lot
