CLEAR MORE THAN ONE UNBOUD TEXT BOX BY CLICKING AN ACTION BUTTON

Hi there,

I have a form which I use for working out the difference between a sales price and cost price of items - the answer is then displayed in the 3rd text box.

I would like to click on a button that will clear the contents of the first two text boxes simultaneously.
I am using ACCESS 2010.

Please forward me an answer to dewaldv4@gmail.com
If it would help. I can email a photo of the form to whomever is able to help me.

Thank you
Dewald
