Making the style change help?

I am making a script where it changes the style when it is clicked. Yes this script works and it is in a for loop but this part of the script does not work. Everything else does, just not this.

if v.Style == "RobloxRoundDefaultButton" then -- there are no errors for this part
	v.Style = "RobloxRoundButton"
else
	v.Style = "RobloxRoundDefaultButton"
end

Ah, I see

v.Style is a ENUM, not a string!

so...

if v.Style == 4 then -- there are no errors for this part
    v.Style = 3
else
    v.Style = 4
end

see the wikidocumentation
