paramAnalysis error when loading data from a form

hello.
i try to run parametric analysis with data that i got from a form and
i get this error " *Error* greaterp: can't handle ("3" > "0") "
using deferent numbers just give the same error but with the different
numbers

the error comes from:
paramAnalysis("my_vb" ?start input_Vb_start ?stop input_Vb_stop ?step
input_Vb_step)

but
analysis('dc ?param "my_vg" ?start input_Vg_start ?stop
input_Vg_stop ?lin input_Vg_lin )
has no problem.

both load data like:
input_Vb_start=test1aa->vbsStart->value
input_Vg_start=test1aa->vgsStart->value

and if i dont load the data form the form (input_Vb_start=0)
paramAnalysis runs fine.

i guess that form data have to be converted to be used in
paramAnalysis???
i cant find any thing in the ocean manual about this problem.

thank you for the help.

Looking at the documentation for paramAnalysis(), it expects the start, stop etc
to be numbers, whereas the analysis() function can cope with them being strings
(containing numbers).

You can use the cdfParseFloatString() to convert the values to numbers:

input_Vb_start=cdfParseFloatString(test1aa->vbsStart->value)

The reason why I used cdfParseFloatString rather than atof(...) is that
cdfParseFloatString() handles suffix notation (e.g. "5n") whereas atof() does not.

i will try it.
thank you very much
