About getting coding free help.
Welcome,
- Usually people who cannot code do not receive free help on this forum, although it could happen if you are lucky. Be patient.
- If you show your attempts and describe your problem clearly, you will most probably receive an answer from the community.
- If you do not want to learn to code, that is not a problem. You can either look at the Codebase if something free already exists, or in the Market for paid products (also sometimes free).
- Finally, you also have the option to hire a programmer in the Freelance section.
Good luck.
--------------------
Just to remind:
Coders (any coder) are coding for free:
- if it is interesting for them personally, or
- if it is interesting for many members of this forum.
and Freelance section of the forum should be used in most of the cases.
