Solution H H h4an Sep 19, 2026 Thanks LucaMs, it worked. I now know what happened, the error came after I updated B4XCollections to V1.15

That "Items As List = Null" is an optional parameter and was introduced in the latest version of B4A, 14.0. Install it and the problem will be resolved (or don't use them). Upvote 0
