Replacing Column Values with Iron Python Script by property Controll

[Stefan Probst]

Hello Community,

I try to use an Iron Python script to change all Values of a column to the Float Value of a property Control (Slider).

This is my Script:

from Spotfire.Dxp.Data import CalculatedColumn

mycalcCol = Document.Data.Tables["test_table"].Columns["new_col"].As[CalculatedColumn]()

myExpression = lowcontrol

mycalcCol.Expression = lowcontrol

with:

lowcontrol = proteryControll value

test_table = DataTable with column to modify

new_col = Column to modify

When I run the script I get following error:

Traceback (most recent call last):

File "", line 5, in

TypeError: expected str, got float

Can someone tell me how to fix this problem The column is defined as Float in my original datatable

I added the Script with error Message as picture to the Post!

Thank you!

Stefan
