Unable to process template language expressions in action 'Update_item' inputs at line '1' and column '16283': 'The template language function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'.

I have a SP List 1 (Leave Entries) and SP List 2 (Leave Balances), I am simply trying to add the new entry ( Whole Days) from List 1 to another column in List 2 (CY Used) but get the above error. I have tried wrapping expression with & without 'int' and 'float' - My flow is below - I appreciate any assistance with this flow or suggestions to do the same thing a different way? it is really frustrating that I cannot fix.

Re: The value cannot be converted to the target type.

After Flow run, (that gives failure) can you please expand Compose 3 and show us what is the result you are getting there?

Re: The value cannot be converted to the target type.

You have written all your formulas as plain text and hence you are seeing failure.

Either write the formula in the Dynamic Content window within the Expression tab, or put your formula as below:

@{ YOUR_FORMULA }

This applies to your Compose and Compose 2 actions as well.

Re: The value cannot be converted to the target type.

Now I have corrected all formulas I believe and created them in the expression builder (see first image), then ran flow and now receive this error at Compose 3?(see second image) If I am still writing the expression wrong please show me the correct formula.

Re: The value cannot be converted to the target type.

Under Compose 3, can you please try:

You have already converted Compose and Compose 2 into int, so no real need to do this again

@{add(outputs('Compose'),outputs('Compose_2'))}

If you do want to explicitly convert to int before add, then use:

@{add(int(outputs('Compose')),int(outputs('Compose_2')))}

Notice that I am using outputs('Compose') within int() and then outputs('Compose_2') in another int() - so my position of closing circular bracket ) is different.

Re: The value cannot be converted to the target type.

Thankyou the below formula worked and the flow works now, can you explain please what adding the wrapping
@{ YOUR_FORMULA }
means? Why doesn't the system accept the expression as written in the expression builder and allow it to save without error?
@{add(outputs('Compose'),outputs('Compose_2'))}
