Did you try text split? http://appinventor.mit.edu/explore/ai2/support/blocks/text.html#split

If you want to build a string 1;2;3;4;5 from an AI2 list L of 5 items 1,2,3,4,5

you would run the list through a csv from list block, then

through a text block that replaces all "," with ";".

Use the text JOIN block to build the URL from the pieces of text, adding more sockets using the blue square.

To pick out the 1;2;3;4;5 from the URL, see https://puravidaapps.com/snippets.php#2parse
parse.aia

and to turn it into a list, reverse the process I described above.
