Maybe you are using some functions that not working on greater versions. Try to set pragram solidity ^0.4.15; if the problem still there, paste here your contract.

@ngCourse Ivan is correct. Using
0.4.15without the^means you are specifying exactly which compiler you are using. If you do^0.4.15, it represents that version and above. Commented Mar 15, 2018 at 13:19 -
i did mention on ^0.4.15 ... it still have that same error Commented Mar 15, 2018 at 13:22

I try in remix.ethereum.org your code and when i change pragma to ^0.4.15 the error disappear. Commented Mar 15, 2018 at 13:25
If you are in a Remix environment just go to settings and change the compiler version.
