hi all-

i am wondering about building more logic into my if/then statements. I can not figure it out so far, I am not sure if its even possible... hoping to get some help or hints.

1.Can an if/then return a string AND calculation result. I have not be able to concatenate this in any way.

I have a if/then to check a value =< limit. If the limit is not exceeded, then the if_true is "Check OK". However, if the if_false should return "Limit Exceeded" and the actual calculated value.

Is this possible? What am I missing?

2. Can I have a combobox as part of an if_then function? If one condition is met, use one combobox, otherwise use a second.

Best regard

Dennis

You are missing some typical work sheet examples !

Hi Dennis,

What about:

concat("result is ",num2str(value))

If you use Custom Functions plugin you can use even:

concat("result is ",var2str(value))

Yes you can have it

Davide-
Thanks for reminding me, when i tried to use concat, i forgot that it was for text strings only.

Here is an example of one application- I am checking historic building members, and if they are overstressed, I want to know by how much.

using num2str, I get a fraction as a result.

if I create a variable, then using var2srt(2) I can control the output format. I would prefer to not have to define the variable, but its workable.

so the conclusion i am getting is the error is in the argument, not the if/then function. here I am using the custom functions with max function

Thanks again
Dennis
