Syntax Error

[Foodie123]

Hello,

I am getting this error I've never seen before. Could someone please explain to me what this error means and what I can do to fix this? 

Any help is appreciated. Thank you.

Share the code please.

It seems you are having a variable as the first parameter and the variable is null.

Make sure the variable has a value and enclose it with single quotation like this '$(vString)'

Here is the code:

let vEvalYrQuarter = Mid(DocumentPath(),117,6);  //ex 201912
     let vEvalYr = mid($(vEvalYrQuarter),3,2);
     let vEvalQuarter = right($(vEvalYrQuarter),2);


Let vLargeLossCutOff=$(vEvalYrQuarter)-500; //Should be 5 Years Prior to eval quarter



let

vAutoLossData='\\Profitability\ActuarialShare\Indications\CW\Auto\$(vEvalYrQuarter)\A$(vEvalYr)$(vEvalQuarter) 16 Loss Datasets.xlsm';

let vAutoTrendData='\\Profitability\ActuarialShare\Indications\CW\Auto\$(vEvalYrQuarter)\Trends - Qlikview\Auto_Trend_Data.xlsx';

Did it work when you changed 

let vEvalYr = mid($(vEvalYrQuarter),3,2);

 to 

let vEvalYr = mid('$(vEvalYrQuarter)',3,2);

?

Yes, this worked! 

Thank you Hesham!
