Error of fixing number in HFSS

Hi everybody,
When i input the index for parameters in floating number like "4.56, 5.34,...", it always automatically change these numbers to integer like this 4, 5,...
Could someone help me fixing it. Thank you so much!

Hi gemmy94,

That's strange, what are the units?

Thank you for considering,planarmaterial. Unit is "mm"

Never seen that before. Where are you putting this data? Into a model object's properties?

You use the word index.

An index is an integer number that is used to identify an element in an array, like data[3] where 3 is the index. So any index would indeed be an integer.
