Help with LessThan

How would I make anysuccess = true IF VAR @Price 70% LessThan VAR @NormalPrice. I want anysuccess = true if the variable price is 70 % lower than variable normalprice

Also how do I prevent \n in content from actually being converted to a new line and actually send \n text in the post request

To prevent \n to be converted to a new line type \\n and for what you want just do x0.3

float PourcentPrice = NormalPrice * 0.3f;

BLOCK:Keycheck
  KEYCHAIN SUCCESS OR
    FLOATKEY @Price LessThan @PourcentPrice
  KEYCHAIN FAIL OR
    FLOATKEY @Price GreaterThanOrEqualTo @PourcentPrice
ENDBLOCK

for the * part it returns “[IDLE] (43,23): error CS0019: Operator ‘*’ cannot be applied to operands of type ‘string’ and ‘float’” when I try to start the config

You have to convert your string to a float first, use the constant float block and put your string variable in there, it will convert it, then use that one.
