I have two fields...

Price is an Amount field Approval is a Person or Group field

so if the Ammount field is > $1000, Approval field is required so what is the proper column formula to validate the Approval field?

For example:

If Amount field >1000, Approval Field cannot be null...

UPDATE:

I just found out the Approval Field doesn't have formula field! Now what?

You can do this using JQuery:

if($('#amountfieldid').val() > 1000){
   if($('#approvalfield').val() == ''){
       alert('Approval field is required!');
       return false;
   } 
}

You can use PreSaveAction() function to write your custom code before submitting the form.

You cannot use lookup fields in Column and List validation or Calculated field , You will have to use

  • The object model to create a validation.

  • Or change Lookup field to Choice Field

  • Or Javascript Validation as something like this

<script type="text/javascript">
    function PreSaveAction() {
        var amount= document.getElementById("Lookup Field ID");
        if (amount.val() > 1000) {
            alert("");
            return false;
        }
        return true;
    }
</script>

  • The lookup field is tied to our active directory groups is I can't use a choice field. What about using Jquery validation? – normsp Aug 22 '16 at 14:32

You can do this with workflow.

  • Create a workflow for this.
  • set this will be fired when an item will be created.
  • check the condition
  • if amount value > 1000 them prompt the user to input Approval field
