Error saving formula - IF statement needs revision

Question

I need to simplify my code, due to the IF formula being too long. This formula is being used in a visualforce page that populates a pagesection based on user input choices.

Can someone help me with shortening this so I no longer get an error?

Answer 1

You shouldn't really be using a formula for this. Build a method in Apex and use the result from that instead:

<apex:pageBlockSection rendered="{!shouldShowSection}">

Which is then a getter method:

public Boolean getShouldShowSection() {
  if(record.Personal_Care__c.contains('Toileting/Bathing/Self-Care in Bathroom' && !record.Physical_Concerns__c.contains('Controlling Environment with Limited Mobility (turning on lights/opening doors)')) {
    return true;
  }
  if(record.Personal_Care__c.contains('Sleeping Routines/Up and About at Night') && !record.Physical_Concerns__c.contains('Controlling Environment with Limited Mobility (turning on lights/opening doors)'))  {
    return true;
  }
  // more if statements here as needed
  // Finally, we return false if the above if statements were not met:
  return false;
}

I suspect it may be possible optimize your conditions further, too, you may want to take more time optimizing your logic.
