Substantial doubt about the company's ability to continue as a going concern.

“Management believes that the Company’s cash and cash equivalents balance of approximately $3.2 million, and the Company’s existing resources, including availability under its $3 million line of credit will not be sufficient to fund the Company’s planned operations and expenditures for at least 12 months from the date of the filing of this Form 10-Q. As a result, substantial doubt exists about the Company’s ability to continue as a going concern.”
