Hi all 
I have an issue which I am not sure why.
Short explanation; I add for a text sentence all words into a table
thisRow.words.FormulaMap(AddOrModifyRows(t_mapping,Description=CurrentValue,Description,CurrentValue))
This works perfect, thanks to @mallika 
But now I have values like
- $5.1
- 2020-2021
Which are added into the table, but won’t show up with the formula.
I believe it’s because this are numbers in a text field
If I change the formula for the lookup e.g. with .ToText() it doesn’t work at all.
Any ideas or suggestions?
Many thanks
Thomas
