Help with spreadsheet formula

[ftneek]

Hello, I'm trying to define a formula for the spreadsheet app using this function

Code:

EXPORT cdf_bin_table(n)
BEGIN
STARTAPP("Spreadsheet");
Cell(0,0):=QUOTE(BINOMIAL_CDF(n,Cell(1,Col),Cell(Row,1)));
END;

However would like 'n' to be replaced with the input value. Can I please get a suggestion on how to do this? I've been trying some different combinations of quote, eval, expr, but with what I've tried so far I still have to replace n manually, or every cell is defined as a string. For reference I'm just recreating a table of values for the binomial cdf, and I've set column A to be Row-2, and put some different probabilities in row 1.
