Storing data from accelerometer

[lonewolf27]

I used the accelerometer code provided in myrio project essentials guide to read the values from accelerometer. I need to store these values atleast for 10minutes but i'm facing trouble doing that. I have tried using "write to measurement file" function as mentioned in the 1st attachment below and got this error :

I have also tried using "write to spreadsheet file" function as mentioned in the 2nd attachment below which also was a failure.
