I am trying to validate a field that has a default value, allow someone to submit a higher value but not allow a lower value. The lower value is dynamic and I would like to set the filed back to the default value. I have tried hooks and custom validators. The field keeps coming back blank, I can’t seem to get the value back in.

works (but static value and can’t reset the field value):
```
&validate=`amount:required:minValue=^500^`
```
doesn’t work:
```
&validate=`amount:required:minValue=[[!+fi.minimum]]`
```
as a hook:
```
<?php
$myAmount = $hook->getValue('amount');
$min = $hook->getValue('minimum');
if ($myAmount<$min){
	$hook->setValue('amount','Default Value');
	$hook->addError('amount','too low');
	return false;
} else {
  return true;
}
```
