SharePoint List Validation When Status is set and No Date

I have a list that I'm trying to write a validation for when a user selects a specific status in a column it verified that they have set the date in another column.

Here is what I have but it is throwing an error:

=IF(AND([Scheduled Status]="Delivery Scheduled", ISBLANK([Scheduled Date])='Yes')

Also trying to write the same type of validation for another column that could have multiple statuses:

=IF(AND([Scheduled PickUp Status]="Store Pickup", ISBLANK([Scheduled Pickup Start Time Date])>Today() and ISBLANK([Scheduled Pickup End Time Date])>Today() AND([Scheduled PickUp Status]="Warehouse Pickup", ISBLANK([Scheduled Pickup Start Time Date])>Today()) and ISBLANK([Scheduled Pickup End Time Date])>Today())
