cursor query gives syntax error for and/or with where clause

I get an SQLite exception in log cat stating that there is a syntax error near "ANDcontraYesOrNo".

Cursor c = db.query( VivzHelper.TABLE_NAME, columns, helper.TX_IDT+"     
='"+name+"' AND" +helper.CONTRA_YES_OR_NO+ "='"+contraY+"' 
OR"+helper.CONTRA_YES_OR_NO+"='"+contraN+"'" +"",null,null, null, NAME + " 
ASC");

Logcat:
