Format Exception when trying to parseFloat(String)

Hello,
I have a problem with my script. For some reason i get a Format Exception when i try to parseFloat() a String that i get from an InputField.

The Exception:

FormatException: Invalid format.

                             Mathf.Cos(d/R)-Mathf.Sin(a1)*Mathf.Sin(a2));
	result.text = a2+"°N "+b2+"°W "; 
}
//

I have no idea what this Exception is telling me. I am a more or less beginner programmer so please don´t be to harsh on me if the structure of the code is not that good.

The “result” variable is a Text variable which gets displayed in the UI.

Here a picture of the UI. (sry for it beeing German but i think that does not matter that much anyway.)

Thanks in Advance!

try float.Parse instead you can also use float.tryParse to handle invalid input

float converted = float.Parse(“17463274”);

Anyone? Could rly use a tip. Maybe i missed something? I have attached everything in the Inspector, so that´s not it.

EDIT WOW I am so stupid haha… I copied the Input Fields so they all still had the first input field function. Thanks for the help anyways, I guess. Took me a few hours to find that stupid mistake but i did find it after all.

Maybe this post helps someone in the future.
