 * Hello,
 * I’m having specific problem with using bracket operator in configuring players
   statistic.
    I’ll try to explain the situation: a) I have these variables in player
   performance: 1. unjevig 2. unjevid 3. nastupdoma 4. nastupgost b) I want to create
   something like this: (unjevig+(unjevid/nastupdoma))/nastupgost+1
 * I’ll try to explain further;
    unjevig = summary of knocked pins on away games
   unjevid = summary of knocked pins on home games nastupdoma = number of appearances
   home nastupgost = number of appearances away
 * I need statistic that have: summery of away game pins + avarage of home pins 
   all divided by appearances away + 1
 * This is the error I’m getting with every version of formula with bracket: [http://luko-delponte.from.hr/test/list/igrac-lige-2-hkls20142015/](http://luko-delponte.from.hr/test/list/igrac-lige-2-hkls20142015/)
 * This is complicated I know, but it’s the only thing I can’t do with this plugin
   and it’s essential for competition 🙂
 * I will appreciate any kind of help!

 * Hi Luko,
 * From the error it looks like there might be mismatched parentheses, which means
   that there are not an equal number of “(” and “)”. I’d be happy to assist you
   further if you could paste in the output of SportsPress > Settings > System Status
   below, using the “code” button.

 * Sorry for bumping the topic but I’ll try to explain further what I need.
    I have
   this variables in player performance: 1. unjevig 2. unjevid 3. nastupdoma 4. 
   nastupgost I want to calculate something like this: =unjevig + ( unjevid / nastupdoma)/
   nastupgost + 1 Only thing that worked with brackets was this formula: =( unjevig
   + unjevid) / ( nastupgost + 1 )
 * Does the nested brackets work?
    Everything else is throwing mismatched parentheses
   error. I updated plugin to version 1.6

 * Ok. I figured it out …
    It looks to me that equation builder isn’t supporting
   nested brackets. Without that there is no way (as far as I know) to solve this
   formula. To bad.. 🙁

 * [@lukodp](https://wordpress.org/support/users/lukodp/) You’re right, the equation
   is throwing an error even though it should be working. The reason this is happening
   is because of a zero-denominator check in sp-core-functions.php: line 1091
 *     ```
       if ( $eos->solveIF( substr( $equation, $pos + 1 ), $vars ) == 0 )
       				return 0;
       ```
   
 * The check is attempting to solve the equation after the first “÷”, throwing a
   mismatched parantheses error because the equation being checked is something 
   like:
 *     ```
       nastupdoma ) ) / ( nastupgost + 1 )
       ```
   
 * I’ll need to fix this part of the check so that it looks for a denominator with
   matching parentheses instead i.e.
 *     ```
       0 !== ( nastupgost + 1 )
       ```
   
 * For now, a temporary solution (if you’re sure that the denominator will not be
   zero) is to comment out the lines in sp-core-functions.php between 1089-1093.
 * I’ll add this issue to our GitHub project for fixing in the next update.

 * A more permanent solution added to core: [https://github.com/ThemeBoy/SportsPress/commit/813eb3fe9001195f6f2ebb650c5bf6a261654ca9](https://github.com/ThemeBoy/SportsPress/commit/813eb3fe9001195f6f2ebb650c5bf6a261654ca9)
 * This checks each sub-equation by splitting the equations wherever a division 
   occurs, then looks at that equation if the parentheses match and return zero 
   if that sub-equation is zero.
 * This version of the zero-denominator check also works properly with your equation
   🙂

 * Hy,
 * I actually give up from that project because of this issue.
    Now I’m starting
   it again here: [http://regijasjever.com.hr/](http://regijasjever.com.hr/) Can’t
