How to work with type record

Thanks for the hint, but I can not assign the exists.version property to an existing variable.

version = exists.version;
leads to a syntax error:
syntax error [M0001], unexpected token ‘=’, expected one of token or sequence

   public func storeAsset(id: Nat32, text: Text) : async ArtId {
    let assetKey = next;
    next += 1;
    
    let version:Nat32 = 1;

    let result = Trie.find(assets, key(id), Nat32.equal);
    let exists = Option.isSome(result);
    switch(result) {
      case(?exists) {
        version = exists.version;
        D.print(debug_show(exists.version));
        D.print(debug_show(version));

      };
      case(null) {
        // entry not found in trie  
      };
    };

    let asset : Asset = {
      id = id; 
      version = version;
      text = text;
    };
    assets := Trie.replace(
      assets,
      key(assetKey),
      Nat32.equal,
      ?asset,
    ).0;
    return assetKey;
  };

How do i update an existing Trie element with the new version of that element, if the key is not Nat32 but is a custom type?
