Change Value of the global variable in Assembly

Hello !

I`m trying to change a variable in assembly by doing the following:

swModel = swApp.ActiveDoc

Dim swEqnMgr = swModel.GetEquationMgr

swEqnMgr.SetEquationAndConfigurationOption(0, """FRAMEHEIGHT""= 123", swInConfigurationOpts_e.swAllConfiguration, Nothing)

swModel.ForceRebuild3(True)

' 0- Global Variable "FRAMEHEIGHT"= 120 index

It doesn`t do anything for me. Am I `missing anything? If I want to change number 123 to the specific variable like Frame.OALHeight how I do that?

Thank you.
