I try to make example from manual:

But expression =EVar(_q*_L^2/8) returns 0. This function works only in this form: =EVar(_q)*EVar(_L)^2/8.

In addition, we have another bug: when I change value of q, for example, value in cell with Evar function return 0. Then, if I want to obtain the result, I go to Preferences, change any unit and press OK. In this case, the value will be updated.

Also I attached text file. Thanks.

EVar function works for a single registered cell only rather than for the whole expression. It searches for the registered in RESC cell and imports information about unit type converting it to the default unit. For the efficiency it is recommended to use EUToBase(...) function instead of EVar. EUToBase and EUToUser contain in their arguments all necessary information to convert values to the default units and vice versa to the display units.

It has to be remembered that each value in the expression has to be included in this formula so that EVar(-q*_l^2/8) is incorrect and is not supported.

But expression =EVar(_q*_L^2/8) returns 0. This function works only in this form: =EVar(_q)*EVar(_L)^2/8.

Please try to use the EUToBase method instead.

Thank you Artur. Syntax of the expression should be =EUToBase(_q*_L^2/8)  ? 

[#4]

=EUToBase(_q;"unit name")*EUToBase(_L;"unit name")^2/8

In "unit name" I have to manually enter units? Can you modify & attach my file from first post? Many thanks in advance.

You can find the list of 'unit names' in 01units.cfg file (see the attached picture). In addition I'm attaching the modified xls.
