i want to be able to click the "Dial" button with my program on Phone Dialer.

What i mean about text1.text thing is...

I have a save option on my program to save phone numbers but if i add the - between the letters it wont work right. EXAMPLE:
"save" is the save code


a= save 972-111-1111
text1.text = a
when loaded text1.text will equal 972
the - blocks it off

so i wana be able to save the number as 9721111111 and save it to text1.text which i can do but i want the program to add in the -'s after its been loaded

text1.text = 9721111111
then user puts mouse on program and it changes to:
text1.text = 972-111-1111

i just made up the number

any ideas?
