Question : combine text data in textboxes on form

Hello,
I have 4 textboxes and command button on a form in access 2000
me.text1, me.text2, metext3, me.text4
if 101 is entered in me.text1
and 102 is entered in me.text2
and  103 is entered in me.text3

Is there a way to code command button to combine these three codes together and display them seperated by commas in me.text4 box?
lke: 101, 102, 103
thank you
