Hi, I use a comma-delimited CSV to decode binary sequences into characters via lookup in pairs. It worked fine, but after modifying the CSV (a change I've done many times), the output now shows extra semicolons: e.g., instead of "hello" I get "h;;;e;;;l;;;l;;;o". The characters are correct and are not repeated, but each is followed by ;;;. We suspect the mistake is one semicolon but it's done three times due to a loop after the lookup, but not sure why it started now. Any ideas?
If necessary, i can upload the code but it's supposed to be related to something related to how MIT APP inventor uses this function in the CSV
