multiple data validation rules for one cell

I need to have multiple data validation rules in a single cell. I've just watched a bunch of tutorials with examples but nothing that fits exactly what I am trying to accomplish. So, I've tried to create my own custom data validation formula...but nothing is working!

Here's an explanation of what I need:

If D52 equals "Small", I need the number the user enters in D55 to be greater than or equal to 220

If D52 equals "Large", I need the number the user enters in D55 to be greater than or equal to 330

So, if "Small" is entered in cell D52, I need an error message to appear if they then enter a number less than 220 in cell D55. At the same time, I need an error message to appear if "Large" is entered in cell D52 and then they enter a number less than 330 in cell D55.

What custom data validation formula can I use in cell D55?

Thank you.

Thank you very much. I thought the solution was likely an OR statement but I couldn't get it quite right. You solution seems to work! Thanks again.

Making sure I understand the consequence of your amendment: does your formula allow an entry less than 330 if cell D52 is blank? Any other consequences or implications?

Thanks!
