 +===== Nested filters =====
 +
 +Sometimes it makes sense to set a filter in another filter. Let's take the situation where, depending on the answer to FF01, either question FF02 or FF03 was displayed. And now, depending on these two questions, another filter should follow. The individual filters would be simple:
 +
 +<code php>
 +if (value('FF02') == 1) {
 +  replace('%stimulus%', 'Dog');
 +} else {
 +  replace('%stimulus%', 'Cat');
 +}
 +</code>
 +
 +<code php>
 +if (value('FF03') == 1) {
 +  replace('%stimulus%', 'Wolf');
 +} else {
 +  replace('%stimulus%', 'Tiger');
 +}
 +</code>
 +
 +But now only one of these two filters should become active ... depending on which value FF01 had. To do this, these filters are placed "inside" another filter.
 +
 +<code php>
 +if (value('FF01') == 1) {
 +  // Filter für FF02
 +  if (value('FF02') == 1) {
 +    replace('%stimulus%', 'Dog');
 +  } else {
 +    replace('%stimulus%', 'Cat');
 +  }
 +} else {
 +  // Filter für FF03
 +  if (value('FF03') == 1) {
 +    replace('%stimulus%', 'Wolf');
 +  } else {
 +    replace('%stimulus%', 'Tiger');
 +  }
 } }
