[Fixed] Calculate Distance Don't Work

[TAV1702]

When creating a schedule, if I enter in my airports from the drop down the hit the calculate link, I get the following return in the field box.

 <br /> <b>Warning</b>:  call_user_method_array() [<a href='function.call-user-method-array'>function.call-user-method-array</a>]: Unable to call calculatedistance() in <b>/home/paranorm/public_html/phpVMS/core/classes/MainController.class.php</b> on line <b>274</b><br />

I just updated to a beta version a few days ago. Prior to that it worked.

If I leave the field 0, it calculates like it should.

Version 1.2.775

Fixed for next beta, thanks!
