i have a switch case condition

switch (this.tHit[i][j]) { case (tHit[i][j]>=kappa-this.bestBias[0][j]): this.gHit[i][j] = 1; case (tHit[i][j] <= kappa - this.bestBias[0][j] && this.tHit[i][j] >= -this.bestBias[0][j]): this.gHit[i][j] = (beta1 * this.bestBias[0][j] + Math.Pow(beta2 * this.bestBias[0][j], 2)) + (beta1 + 2 * beta2 * this.bestBias[0][j]) * tHit[i][j] + beta2 * Math.Pow(tHit[i][j], 2); case (this.tHit[i][j] <= -this.bestBias[0][j] && tHit[i][j] >= -kappa - this.bestBias[0][j]): this.gHit[i][j] = (beta1 * this.bestBias[0][j] - Math.Pow(beta2 * this.bestBias[0][j], 2)) + (beta1 - 2 * beta2 * this.bestBias[0][j]) * tHit[i][j] - beta2 * Math.Pow(tHit[i][j], 2); case (this.tHit[i][j]<=-kappa-this.bestBias[0][j]): this.gHit[i][j] = -1; }

and i got an error in switch(...) : Error 1 A value of an integral type expected

what it mean about? please help me.

thanks before.
