Trouble calculating into a global

Hello, I'm having trouble calculating a value into a global.

I have a formula in Excel that is giving me the right value.

When I build it in App Inventor then the result is different than the Excel value.

I think I'm doing somthing wrong but can't work it out.

Any suggestions. Thank you!

If the comma in the formula is decimal point, then your blocks look right. Do you have the correct dphi and dlam??

Try breaking it down as follows and see if you get the right answer.

temp1 = dphi*0.329

temp1 = temp1 - 37.902

temp2 = dlam * 14.667

temp2 = temp1 - temp2

temp2 = temp2 * 0.00001

Deeply nested blocks can be made easier to read if you right-click-ExternalInputs on them.

The nesting becomes more clear.

Are you sure that you are using decimal . Instead of decimal , for the values entered ?
In AI2 you can only use . Irrespective of your country settings.
