Error while trying to Update XML

[LoveNintex]

Hello,

That worked - I put the whole XPath Query string in a variable instead of the just the index value and it worked.   

I have seen other people use a variable in just the index, and it worked for them so I tried to figure out why it wasn't working for me.  Turns out that the "value" I was trying to use was not compatible with the field I was trying to put it in.  When I changed the value, I was able to use the variable in the index.  @kchaluvadi but, I would not have been able to figure it out, if it wasn't for you.  Thank you!
