Moving to next V if target is unreachable?

[MGCLegend]

I have been quite the needy person today so sorry for that, however, I have great motivation to learn.
So,
I am coding an entity to find other ents as v in pairs using ents.FindByClass
The issue is that I cannot figure out how to change v if v is greater than 1000 units

Here is example code:

if self.MelonMode == "search" then
		print("A Melon is in Search Mode")
		--start shooting any enemy melons it can see
		for k,v in pairs(ents.FindByClass("melon_blue")) do
				print("A Melon Searched For Ents")
				if v then print("A Melon found Ents: ") print(v)
					local selfEntPos = self:GetPos()
            if selfEntPos:Distance( v:GetPos() ) > 1000 then return false end --if its greater than 1000 then restart, but how to find a new v instead of the same?
			
				self:PlayAlertedSound()
					elseif v then return false end
			if v.MelonMode == "dead" then return end

Just put all of the code inside an if statement.

for blah blah do
    if v < 1000 then
        --Code in here
    end
end

Is that what you're after? I could not quite understand.

The target is v. If v is less than 100 units away, it will target that. If not, it would search again. Problem is when it searches again, it finds the same v.
*rated myself dumb for this*
