[SOLVED] Qt moc_file issues

I'm a student programmer and I am using Qt to build some GUI applications for work and I have been running into moc issues over and over again. I was hoping for a solution to the current problem that I am having; however, if anyone more veteraned in Qt could shed some light on how to properly handle these files while making changes to your cpp file(s) I'd appreciate any help. In my most recent change (sorry I can't post what it did look like, because it's obviously been restructured) I was validating data by nesting a function inside of my checkData function. Because I would like a specific error to appear for each field that might be invalid I began to create a function for each QLineEdit. I realized that this would not work (or at least make more work) then instead of just providing sequenced checks of information. Below is the new code without the original nested function:

void InjectionDialog::checkData() {
   bool validateFluidVelocity;
   QString tempStrFluidVelocity;
   tempStrFluidVelocity = ui->lineEditFluidVelocity->text();
   double convertedFluidVelocity =
      tempStrFluidVelocity.toDouble(&validateFluidVelocity);
   if (validateFluidVelocity == false) {
      QErrorMessage validateErrorFluidVelocityError;
      validateErrorFluidVelocityError.
         showMessage("Fluid velocity input is invalid");
      validateErrorFluidVelocityError.exec();
   }
   else {
      transData.lineEditFluidVelocity = convertedFluidVelocity;
   }
   bool validateFluidMassFlow;
   QString tempStrFluidMassFlow;
   tempStrFluidMassFlow = ui->lineEditFluidMassFlow->text();
   double convertedFluidMassFlow =
      tempStrFluidMassFlow.toDouble(&validateFluidMassFlow);
   if (validateFluidMassFlow == false) {
      QErrorMessage validateErrorFluidMassFlowError;
      validateErrorFluidMassFlowError.
         showMessage("Fluid mass flow input is invalid");
      validateErrorFluidMassFlowError.exec();
   }
   else {
      transData.lineEditFluidMassFlow = convertedFluidMassFlow;
   }
   bool validateParticleVelocity;
   QString tempStrParticleVelocity;
   tempStrParticleVelocity = ui->lineEditParticleVelocity->text();
   double convertedParticleVelocity =
      tempStrParticleVelocity.toDouble(&validateParticleVelocity);
   if (validateParticleVelocity == false) {
      QErrorMessage validateErrorParticleVelocity;
      validateErrorParticleVelocity.
         showMessage("Particle velocity input is invalid");
      validateErrorParticleVelocity.exec();
   }
   else {
      transData.lineEditParitcle_sic_Velocity = convertedParticleVelocity;
   }
   bool validateParticleMassFlow;
   QString tempStrParticleMassFlow;
   tempStrParticleMassFlow = ui->lineEditParticleMassFlow->text();
   double convertedParticleMassFlow =
      tempStrParticleMassFlow.toDouble(&validateParticleMassFlow);
   if (validateParticleMassFlow == false) {
      QErrorMessage validateErrorParticleMassFlow;
      validateErrorParticleMassFlow.
         showMessage("Particle mass flow input is invalid");
      validateErrorParticleMassFlow.exec();
   }
   else {
      transData.lineEditParticleMassFlow = convertedParticleMassFlow;
   }
}

Initially I had InjectionDialog::checkFluidVelociy for the first check but decided against it pretty quickly. Now with the code restructured I receive the error:

In function 'InjectionDialog::checkFluidVelocity(QMetaObject::Call, int, void**)': this error is referenced to moc_injectionDialog.o

unidentified reference to 'InjectionDialog::checkFluidVelocity()' this error is referenced to moc_injectiondialog.cpp

In moc_injectiondialog I have the following I have the following listed:

I have looked over some of the other moc_file posts and most of them say to have Qt clean and rebuild the project. I have ran a project clean up and rebuild all to try to overhaul this moc file but have not had any success in getting rid of the error. It seems like a bug but I couldn't find anything online about it so maybe it's something I don't know about. Thanks in advance for any help you can offer.
