K, I can't wrap my head around why this error keeps popping up. I am writing a conversion program and thanks to some prior help, I am able to start calculating some values, but I've run into a bit of a snag. Examples below:

My defines:
Qt Code: 
  1. #define ACRE_SQ_CHAIN       10;
  2. #define ACRE_RODS           160;
  3. #define ACRE_SQ_LINKS       10000;
  4. #define ACRE_HECTARE        0.4047;

and the calculation routine - this works:
Qt Code: 
  1. if(to == "Hectare")
  2.         {
  3.             cvrt = temp * ACRE_HECTARE;
  4.             answer.setNum(cvrt);
  5.             leAcreAns->setText(answer);
  6.         }
To copy to clipboard, switch view to plain text mode 

This doesn't work:
Qt Code: 
  1. if(to == "Rods")
  2.         {
  3.             cvrt = temp / ACRE_SQ_CHAIN * ACRE_RODS;
  4.             answer.setNum(cvrt);
  5.             leAcreAns->setText(answer);
  6.         }
To copy to clipboard, switch view to plain text mode 
This is the section that is throwing the 'unary error'. If I change ACRE_RODS to the actual hard coded value, that is 160, error still occurs. Why is it that in some cases, it figures out I want to multiply the values, but in other cases, it thinks there is a unary * issue....

If you look at the first section where it have temp * ACRE_HECTARE, that works fine, but, if I reverse it, so that it reads, ACRE_HECTARE * temp, it also throws the unary* error? What am I not seeing??

Thanks!
