Hi, BluGeni.

I understand wanting to remove negative signs within a block of text. However, you show variables $busi1 .. $busi3 in substitution operations, and a variable $i taking values 0 .. 31 as a subscript used in a for loop, viz., $busi[$i]. Additionally, you mention "negatives that may be entered into a text box," perhaps suggesting a single text box within a Web form.

How many text boxes are you working with in your Web form: 1, 3, 32, other? How is/are the value(s) from the Web form accessed from within your script (e.g., by using CGI's params function)?
