clear textbox if all checkboxes are false

Hello Everyone,

Need help here. I already attached the sample file.
Per frame I have 3 checkboxes and a textbox. Example: I clicked on checkbox1 then caption will be shown on the textbox as shown however what I need help for is that if all textboxes are false then the textbox should be blank as well.
I tried this code:

however I still have to double click the next checkbox I need to choose just to have it show on the textbox and it's not user friendly.

Just to give a summary:
If checkbox1,2,3 = false then textbox1.value = 1 and if checkboxes must only be clicked ONCE to have the caption added to the textbox.

I hope someone can help me out. Thank you.


UPDATE: there are 2 frames:
If the checkbox value = 1 from frame 1 is checked then
checkbox value = 1 from frame 2 should be blank and also the rest of the values to the frame1 checkbox2,3 = false

Can I suggest to use four option buttons (1,2,3 and None) instead of checkboxes. Optionbuttons are for when there is only one choice allowed. Checkboxes are usually used when multiple choices are allowed.

I appreciate the help however I forgot to mention that
example:
Frame 1
checkbox1.caption = 1, checkbox2.caption = 2, checkbox3.caption = 3
textbox1

Frame 2
checkbox4.caption = 1, checkbox5.caption = 2, checkbox6.caption = 3
textbox2


if checkbox1 = true then all checkbox2 , checkbox3, checkbox4 = false
textbox1 = "1"
else
textbox1 = ""

if checkbox4 = true then checkbox1 , checkbox5, checkbox6 = false
textbox2 = "1

else
textbox1 = ""
