Error at _cmdno 26 executing "solve" command

[Vivi]

Dear AMPL team,

I am reading my data from spreadsheet and I have a set of only one member and a parameter related to this set. The Excel file is attached. And in the .run file to read the spreadsheet I have thoses statements:

table EPSI_tab IN "amplxl" "EPSI_VAL.xlsx" "epsi":
  [EPSI ], EP_VAL; 

read table EPSI_tab;

And I have had the following error  message:

«error processing param EP_VAL[...]:
no data for set EPSI
ampl: »

Thank in advance for your help.
