CAN ANYONE HELP FIX MY C++ CODE

https://pastebin.com/L4p2dpk4

My code is there ^^

 **   if ((drug_potency_loss < 100 && drug_potency_loss > 0) && (target_effectiveness > 25 && target_effectiveness < 100)) {
        cout << "Potency loss = " << drug_potency_loss / 100.00 << endl; // This will calculate the potency loss in decimal numbers instead of percentage numbers.
        cout << "Target effectiveness = " << target_effectiveness << endl; // cout statement tells the user the target effectiveness.
        cout << " " << endl; //creates a blank line.
        cout << "Determining drug effectiveness: ..." << endl; // cout statement.
        cout << "" << endl; // blank line.
    }**

(Lines 22-28)

With this code, the user is supposed to enter -4 50

and then it will say error, try again

101 (error)

100 (error) and then 4 (the code will work)

but the output from my code won't show.

However, whenever I type in 4 50 for the first time, the output shows. I put all of my code in a do-loop but for some reason, the output that is bolded will only appear whenever I type in the correct numbers.

I'm trying to make that specific part of the code show regardless of the attempts tried.

That's all I needed help fixing.

AND YES THE CODE COMPILES AND THE LOOP WORKS
