Transfering data from a table to another database

i have a server connect file which doesn’t let me edit the database query in it. I’m copying data from one table to another table in another mysql database. I’m using a repeat to transfer the data. it worked once, but now it doesn’t work and when I try to edit the query, nothing happens when I try to open the query builder. Is there a way to edit this without having to rewrite the file?

Thanks,
Rick
