Organization, Consolidated and Presentation of Financial Statements [Abstract]  
Organization, Consolidated and Presentation of Financial Statements
1.   The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and article 10 of Regulation S-X and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  Therefore, these financial statements should be read in conjunction with the annual report on Form 10-K for the fiscal year ended April 30, 2012.  In our opinion, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been included.  Operating results for the three months ended July 31, 2012 are not indicative of the results of operations that may be expected for the fiscal year ended April 30, 2013.
