Why is this expression invalid?

Can anybody help me troubleshoot this expression? I'm just not seeing where the problem is. I also can't get the tooltips thing to show up in the expression editor to help me.
 
If(greater(variables('Conduct2'),50),null,concat('<img src=',variables('firebrick'),' height="25" width="',string(sub(50,(variables('Conduct'))),'">'))
 
Thanks.

Re: Why is this expression invalid?

Hi @Anonymous,

 

It seems that you are trying to concat a URL of an image.

I have tested the following code, please check it for a reference:

if(greater(variables('Conduct2'),50),'',concat('<img scr="',variables('firebrick'),'"','height="25" width="',string(sub(50,variables('Conduct'))),'">'))

Please take a try with it on your side.

 

Best regards,

Mabel

Re: Why is this expression invalid?

Thanks Mabel,

I see the problem now. I was trying to use the single quote variant of the <img> tag (because the variable I'm refrencing is a data URI), forgetting that I need to use an escape character '' , or else Flow thinks it's part of an expression, rather than a string.

Your way, with the double quotes, also works, but if you're trying to embed your image with a data URI, you need 2 single quotes in a row.
