Ropsten contract execution [Reverted]

Question

Can someone help me and tell me where in my code is the problem. How to fix this ?

Is there any obvious error ? Help is more than appreciate.Robert

When sending ether to the contract address it would call this function in your contract:

function () payable whenNotPaused beforeDeadline afterStartTime saleNotClosed  {
    require(msg.value >= minContribution);

    // Update the sender's balance of wei contributed and the amount raised
    uint amount = msg.value;
    uint currentBalance = balanceOf[msg.sender];
    balanceOf[msg.sender] = currentBalance.add(amount);
    amountRaised = amountRaised.add(amount);

    // Compute the number of tokens to be rewarded to the sender
    // Note: it's important for this calculation that both wei
    // and PDT have the same number of decimal places (18)
    uint numTokens = amount.mul(rate);

    // Transfer the tokens from the crowdsale supply to the sender
    if (tokenReward.transferFrom(tokenReward.owner(), msg.sender, numTokens)) {
        FundTransfer(msg.sender, amount, true);
        // Check if the funding goal or cap have been reached
        // TODO check impact on gas cost
        checkFundingGoal();
        checkFundingCap();
    }
    else {
        revert();
    }
}

The transaction would be reverted if either:

• contract is paused
• after deadline
• before start time
• sale is closed
• value is less than minimum contribution
• funding goal or cap has been reached
