I have my x-values in Data1_A and I am trying to execute the following script to calculate the y-values (and store them in column Data1_D):

Ea=10000;
H=1000;
Tu=350;
Data1_C=exp((-Ea/(8,314))*((1/(Data1_A))-(1/Tu)));
integrate Data1_C;
Data1_D=H*Data1_C*exp(-(_integ_area));

My problem is I don't get any values in column Data1_D?

The variable "Ea" is not initialized.

Sorry I forgot to copy the first line:

Ea=10000;

I have tried to initialize all variables, but it doesn't solve my problem.

Hi,

I think the problem is the number format,

In the line

Data1_C=exp((-Ea/(8,314)) .....

I change the number 8,314 to 8.314 and it worked on my computer.

(The result might depend on regional settings in Control Panel)
