Script variable dollar expansion help

[Deadpool]

Hi

I can normally figure these out but this has had me banging my head against the wall.

On the tab I have an Input Box with a variable called vOHD which contains a decimal that the user can change.

I am trying to create a dynamic title for a chart which references the vOHD value (and displays it as a percentage).  I want to store that in another variable which I want to create in the load script. 

Example: 'OHD (' & num($(vOHD),'0%') & ')' which would show OHD (20%).

The trouble I am having is stopping the vOHD doing the dollar expansion and returning the result during the load.  Normally to avoid this I would do something like this: 'OHD (' & num($' & ' (vOHD),'0%') & ')' but I can't seem to get the correct combination to get the vOHD not to calculate too soon or not to calculate at all when enclosing the chart label in $().

example of one of many failed syntax:

set x = 'OHDs (@ ' & num($'&'(vOHD),'0%') & ')';

Please can you help?

Not sure if I understand your issue correct. Is this what you want:

Not: set SEt_x = 'OHDs (@ ' & num($'&'(vOHD),'0%') & ')';

But: let let_x = 'OHDs '& $(vOHD)&' %';

The easiest way would just be not to define these variables within the script else within the UI variable-editor. IMO there is not much benefit to do it within the script else it costs only efforts and is error-prone.

Should it be really within the script you need to replace the $ with anything else maybe with something in this way:

set x = "num(DOLLAR(vOHD),'0%')";
let x = replace('$(x)', 'DOLLAR', '$');

Another approach would be to read these variable-definitions from a file and then looping through the records and then assigning field-values to your variables.

But like above mentioned my first suggestion is the easiest way and you should have good reasons to take the extra costs for the script-approaches.
