Issues with 'strategy.position_avg_price'

Hey guys, hope everyone is doing fine. I'm new to pinescript coding and I'm having a fairly simple (I guess) issue that manages to mess up my day entirely.... In my code I have the following lines:

// Calculate entry price for long position
entryPriceLong = strategy.position_avg_price(Long Entry)

// Calculate entry price for short position
entryPriceShort = strategy.position_avg_price(Short Entry)

However, this error message is prompted:
Could not find function or function reference 'strategy.position_avg_price'

Thanks for anybody that finds the time and manages to save my day!

Hi Dominik

The variable strategy.position_avg_price doesn't take a parameter between parentheses
Documentation: https://www.tradingview.com/pine-script-reference/v5/#var_strategy.position_avg_price

The code should be

if strategy.position_size > 0 // Long
    entryPriceLong = strategy.position_avg_price
else if strategy.postion_size < 0 // short
   entryPriceShort = strategy.position_avg_price
