Cannot Convert value of type text to type true false

Hi,

 

I am getting increasingly frustrated with the above error message as I can't understand why it's appearing for the below formula as all fields involved are text.

 

Does anyone have any ideas where I'm going wrong?

 

Thanks in advance


    IF(
        LOOKUPVALUE(CIS[companyID],CIS[DUNSNUM],GUODataCombine[DUNS],CIS[CompanyName],GUODataCombine[PartyName]),
        "Found", 
        "Not Found"
    )

Hi @lgs1983 ,

The test you are making is returning a text value, not a true false value. Now if you could frame it so that is Lookupvalue(CIS[CompanyID]) = x, then it can evaluate that. You will probably end up using  && for multiple tests, or you could try ISBLANK(). But your test needs something to evaluate.

 

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

Hi @lgs1983 ,

You may want to try ISBLANK()

Checks whether a value is blank, and returns TRUE or FALSE. The function surrounds the value you are testing.

However BLANK() returns a blank.

Thanks @Nathaniel_C , it was me taking it for granted it would see the lookup as a true or false automatically, now amended to the following and works:

 

    IF(
        LOOKUPVALUE(CIS[companyID],CIS[DUNSNUM],GUODataCombine[DUNS],CIS[CompanyName],GUODataCombine[PartyName]) = BLANK(),
        "Found",
        "Not Found")
    )
