# Re: [QF-Test] How to compare the component displayed value

```Hi Greg,

I've tried to use Fetch Text node to get the text value from the global variable as shown in FetchTextComparision jpg,
but the value of the variable returned from Fetch text node is not dynamic, so for instance, I used record check text to get the component id, and if the variance is 0.00 then the component id is label0.00; and if the variable is -64.00 then the component id is label-64.00
therefore the variable always hold the original component's value because I specified the variance component's id to be label0.00 even though label-64.00 and label-0.00 should be the same component based on they are at the same position on the GUI panel.
Is there a way to get the actual different value of the label for the same label component as you can see in the variance amount jpg (the label representing the amount is next to the variance label)?

Best regards
Kevin

Hi Kevin,

the problem is that you are using rc.getComponent as the test in an 'If' node. You can't do that because rc.getComponent is solely available in the SUT whereas 'If' node tests are evaluated in QF-Test's Jython interpreter.

Instead, use a 'Fetch text' node to read the text of the intended target component and store it in a variable, e.g. "text", then use

rc.lookup("text") != "0.00"

in the test of the 'If' node.

NB: In general rc.lookup("text") is preferable to "\$(text)" because it doesn't throw an exception in case of line breaks or special escape sequences.

Best regards,
Greg
