Remix Gas limit exceeded regardless of how high I set it

I am deploying a crowdsale contract in Remix but no matter how high I set the gas limit (set it to 40000000 once) or even how much I change the value field I can't get this contract to not exceed the gas limit. The other contract I deployed was much larger and it deployed fine so I am thinking there is something wrong with my code. Here it is pragma solidity ^0.4.19; /** * @title SafeMath * @dev Math operations with safety checks that throw on error */ library SafeMath { function mul(uint256 a, uint256 b) internal constant returns (uint256) { uint256 c = a * b; assert(a == 0 || c / a == b); return c; } function add(uint256 a, uint256 b) internal constant returns (uint256) { uint256 c = a + b; assert(c >= a); return c; } } /** * @title Ownable * @dev The Ownable contract has an owner address, and provides basic authorization control * functions, this simplifies the implementation of "user permissions". */ contract Ownable { address public owner; /** * @dev The Ownable constructor sets the original `owner` of the contract to the sender * account. */ function Ownable() { owner = msg.sender; } /** * @dev Throws if called by any account other than the owner. */ modifier onlyOwner() { require(msg.sender == owner); _; } /** * @dev Allows the current owner to transfer control of the contract to a newOwner. * @param newOwner The address to transfer ownership to. */ function transferOwnership(address newOwner) onlyOwner { require(newOwner != address(0)); owner = newOwner; } } /** * @title Token * @dev API interface for interacting with the BQPOT Token contract */ interface Token { function transfer(address _to, uint256 _value) returns (bool); function balanceOf(address _owner) constant returns (uint256 balance); } contract Crowdsale is Ownable { using SafeMath for uint256; Token token; uint256 public constant RATE = 1000; //Tokens per Ether uint256 public constant CAP = 73; //Cap in Ether uint256 public constant START = 1517383764; //Must change for timestamp uint256 public DAYS = 1; //Preorder lasts for 14 DAYS bool public initialized = false; uint256 public raisedAmount = 0; // Who bought tokens and how many? event BoughtTokens(address indexed to, uint256 value); //Is the sale active? modifier whenSaleIsActive() { assert(isActive()); _; } //Pass in token contract address function Crowdsale(address _tokenAddr){ require(_tokenAddr !=0); token = Token(_tokenAddr); } //Makes sure there is correct amount of tokens sent to address function initialize(uint256 numTokens) onlyOwner { require(initialized == false); require(tokensAvailable() ==numTokens); //Make sure tokens are available initialized = true; //If they check out set initialize to true } function isActive() constant returns (bool) { return ( initialized == true && //Is contract initialized? now >= START && //To be active it must be after the start date now <= START.add(DAYS * 1 days) && //Before end date goalReached() == false //Also Goal is not yet reached ); } function goalReached() constant returns (bool) { return (raisedAmount >= CAP * 1 ether); } function () payable { buyTokens(); } function buyTokens() payable whenSaleIsActive{ uint256 weiAmount = msg.value; uint256 tokens = weiAmount.mul(RATE); BoughtTokens(msg.sender, tokens); //Add to amount raised raisedAmount = raisedAmount.add(msg.value); //Send buyer tokens token.transfer(msg.sender, tokens); //Send ether to owner owner.transfer(msg.value); } //Return number of tokens allocated to contract function tokensAvailable() constant returns (uint256) { return token.balanceOf(this); } //Stop contract and refund the owner function destroy() onlyOwner { //Send rest of tokens to the owner uint256 balance = token.balanceOf(this); assert(balance > 0); token.transfer(owner, balance); //Incase ether is left in contract selfdestruct(owner); } }

I'm not sure but could be this : When deploying you instance the following instruction : token = Token(_tokenAddr); However Token is defined as the following : interface Token { function transfer(address _to, uint256 _value) returns (bool); function balanceOf(address _owner) constant returns (uint256 balance); } I'd see two points here : This is an interface, not a contract and so shouldn't be used as instanciable directly ( it should be used to base another contract ). Even if it wasn't an Interface there is not constructor in it, and event with constructor, you should have to specify an argument in the signature call of the constructor as you pass an argument on deployment.

I deployed your CrowdSale contract in Remix IDE using the Javascript VM with no issues. creation of Crowdsale pending...
