Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).  A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account.  These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance.  During its most recent fiscal year, the Fund had a portfolio turnover rate of 173% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of small capitalization companies that the Fund’s investment adviser, Timpani Capital Management LLC (“Timpani”), believes have sound growth potential.  For purposes of the 80% policy, net assets include any borrowings for investment purposes.  The Fund may invest up to 25% of its total assets in American Depositary Receipts (“ADRs”) and other foreign securities.  Timpani uses fundamental research, focusing on companies with superior management and whose business models have a high potential for earnings upside.  Timpani may actively trade portfolio securities.

Risk [Heading] rr_RiskHeading Principal Investment Risks.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Market Risks.  The Fund’s investments are subject to market risk, which may cause the value of the Fund’s investments to decline.  If the value of the Fund’s investments goes down, the share price of the Fund will go down, and you may lose money.  U.S. and international markets have experienced extreme volatility, reduced liquidity, credit downgrades, increased likelihood of default and valuation difficulties in recent years.


Stock Selection Risks.  The stocks selected for the Fund may decline in value or not increase in value when the stock market in general is rising.


Equity Securities Risks.  Common stocks and other equity securities held by the Fund will fluctuate in value based on the earnings of the company and on general industry and market conditions, leading to fluctuations in the Fund’s share price.


Foreign Securities Risks.  Investments in securities of foreign companies involve additional risks, including less liquidity, currency-rate fluctuations, political and economic instability, differences in financial reporting standards and securities market regulation, and imposition of foreign withholding taxes.


American Depositary Receipts Risks.  The risks of ADRs include many of the risks associated with investing directly in foreign securities, such as currency-rate fluctuations and political and economic instability.


Portfolio Turnover Risks.  The Fund may engage in frequent trading as part of its investment strategy and thus may experience a high portfolio turnover rate.  When the Fund experiences a high portfolio turnover rate, you may realize significant taxable capital gains as a result of frequent trading of the Fund’s assets and the Fund will incur transaction costs in connection with buying and selling securities, which may lower the Fund’s return.


Liquidity Risks.  Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time and price that Timpani would like to sell.  Timpani may have to lower the price, sell other securities instead or forego an investment opportunity.


Growth Investing Risks.  Growth companies are generally more susceptible than established companies to market events and sharp declines in value.  Additionally, growth stocks typically lack the dividend yield that can cushion stock prices in market downturns.


Small Capitalization Risks.  Securities of companies with small market capitalizations are often more volatile, less liquid and more susceptible to market pressures than securities of larger companies.


Management Risks.  The Fund is subject to management risk as an actively-managed investment portfolio and depends on the decisions of the portfolio manager to produce the desired results.

Risk Lose Money [Text] rr_RiskLoseMoney If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money.
