Hi 

i just paste a pcf formula found in the discussion, i still have error with "unable to parse number 0.50 or 0.60 or 0.40 ...

how can i correct that?

Thank you

The best option would be to re-write the formula to avoid the use of decimal markers. For example, you could change something like the following.

L + 0.50 * (C - O)

Into:

L + (C - O) / 2

Or:

L + 0.60 * (C - O)

Into:

L + 6 * (C - O) / 10

Or something like the following:

O >= 1.05 * C1

Into:

100 * O >= 105 * C1

The exact manipulation will depend on the particular formula, but it should possible to convert all formulas using this basic method.
