Using MathType Word SDK to convert equations

[generic_name]

Hi all,

I am trying to use the MathType Word SDK to convert Word equations to MathType equations and am running into an error. I implement a variable of type ConvertEquationsInfo and assign all of the 'sub' variables in it and then pass this to the ConvertEquations sub as it asks for (see documentation for this). When I do this it raises the error "Variable required - Can't assign to this expression" and I'm unsure why?

MathType SDK Documentation (https://docs.wiris.com/en/mathtype/office_tools/mathtype-sdk/apidocumentation#convertequations) including ConvertEquationsInfo type definition.

Code:

Sub MathTypeConversion(Optional ByVal control As IRibbonControl)
Dim info2 As ConvertEquationsInfo
info2.equationTypes = mt_CVT_FIND_WORDEQ
info2.promptUser = False
info2.showStats = False
info2.selectionOnly = True
info2.translatorFileName = ""
info2.translatorOptions = mt_CVT_TRAN_MTEF
info2.count = 1
ConvertEquations (info2)
End Sub


Any help would be appreciated as I am relatively new to VBA. Please if I have missed key information let me know and I can supply any required for clarification.

Cheers
