I'm trying to have a text field required when a value is selected in Multi-picklist field

    AND(TEXT(Environment_Access__c ) = "DevQA", 
        ISBLANK( Business_Justification__c )),

First of all, you can always replace IF(condition, true, false) with just condition.

Second, you need to use INCLUDES rather than TEXT.

    INCLUDES(Multi_Picklist__c, "SingleOption"),
  • That worked i appreciate it

For checking a value in multi select picklist, you will have to use INCLUDES

Your validation rule should be like this

IF(AND(INCLUDES(Environment_Access__c, 'DevQA'), ISBLANK(Business_Justification__c)), true, false)  


AND(INCLUDES(Environment_Access__c, 'DevQA'), ISBLANK(Business_Justification__c))
