Help with robot C programming

Hello
We put tank control, arm movement and intake movement inside a repeat forever bracket but only the one that is in the top of the 3 blocks works
For example- if inside the repeat forever bracket tank control is first only rank control will work

Any help?
We are using robot C with the blocks

First of all I would recommend transitioning to VEXcode for iq if possible.
and could you please send your code so we could better assist you
