Here are some code snippets.
I always tried to use fields, but for some things I used a scratchpad tiddler called StoreDailyQuestionaireData. If I would use the same in those case, then I'd get rendering issues.
! My happiness levels are
<$radio field="q-happiness-levels" value="1"> abysmal low</$radio>
<$radio field="q-happiness-levels" value="2"> very low</$radio>
<$radio field="q-happiness-levels" value="3"> low</$radio>
<$radio field="q-happiness-levels" value="4"> medium</$radio>
<$radio field="q-happiness-levels" value="5"> high</$radio>
<$radio field="q-happiness-levels" value="6"> very high</$radio>
<$radio field="q-happiness-levels" value="7"> extremely high</$radio>

! I slept
<p class="sleep-time-interval">Time Interval: <$view field=sleep-time-interval_value/> <$edit-text tiddler="StoreDailyQuestionnaireData" field="sleep-time-interval_value"/> <$button><$action-setfield $field=sleep-time-interval_value $value={{StoreDailyQuestionnaireData!!sleep-time-interval_value}} /><$action-setfield $tiddler="StoreDailyQuestionnaireData" $field="sleep-time-interval_value" $value="" /> change sleep-time-interval</$button> <span class="subtitle"> (E.g. format: 23:49 - 03:57, 06:37 - 10:47)</span></p>

! How many cups coffee did you drink?
<$range field="coffee-amount" min="0" max="10" default="0" increment="1"/> <$transclude field="coffee-amount" />
